What Is Audi Navigation Plus?

Audi Navigation Plus is a name used for factory Audi navigation and multimedia systems.

Different generations and hardware versions have existed, so two systems described as Navigation Plus may not necessarily be identical.

Depending on the exact unit, Navigation Plus can combine functions such as:

• Factory radio
• Navigation
• Audio playback
• Multimedia controls
• Vehicle audio-system integration
• Steering-wheel control integration

For this reason, the Navigation Plus name alone is not enough to determine the exact security procedure.

Always identify the actual navigation unit.

Audi Navigation Plus Radio Code

A compatible Audi Navigation Plus unit may use a numerical anti-theft security PIN.

A code request may appear after:

• Battery disconnection
• Battery replacement
• Complete electrical power interruption
• Navigation-unit removal
• Navigation-unit reinstallation
• Replacement unit installation
• Installation of a used unit
• Electrical repairs
• Dashboard work

If the system displays a normal numerical PIN-entry screen, the correct security-code information may be required before normal operation can continue.

Audi Navigation Plus AUZ Serial Number

Many factory Audi radios and navigation units use an identification number beginning with:

AUZ

The complete AUZ sequence identifies the individual unit.

Do not submit only the letters AUZ.

The complete serial number is important.

Depending on the exact navigation system, the label may also contain:

• Audi part number
• Model information
• Manufacturer information
• Hardware version
• Production information
• Barcode
• Additional identifiers

Always provide the exact information requested for your unit.

Where Can I Find the Audi Navigation Plus Serial Number?

The identification information is commonly printed on a label attached to the navigation-unit chassis.

Depending on the installation, the unit may need to be pulled forward or removed from the dashboard to access the label.

If removal is required, take care with:

• Dashboard trim
• Electrical connectors
• Antenna connections
• GPS connections
• Wiring
• Mounting hardware

If you are not comfortable accessing the unit yourself, consider having an experienced automotive technician or car-audio installer remove it safely.

Once you have the required identification information, you do not need to ship the navigation unit to us.

Check Your Audi AUZ Serial Number Carefully

Accurate identification is essential.

Compare every character directly with the original identification label.

Pay particular attention to similar-looking characters:

0 and O

1 and I

5 and S

8 and B

Never guess an unclear character.

One incorrect character may prevent correct radio identification.

If the label is faded, damaged, scratched, or difficult to read, contact us with a clear photograph before ordering.

Audi Navigation Plus RNS-E Radio Code

Some Audi navigation systems commonly associated with the Navigation Plus name may be identified as RNS-E.

A compatible RNS-E unit may use a numerical anti-theft PIN.

If your system is specifically identified as RNS-E, locate the complete radio identification information before ordering.

Do not rely only on the Navigation Plus name.

The exact unit is more important.

Audi Navigation Plus RNS-D Radio Code

Earlier Audi navigation systems may be associated with RNS-D.

RNS-D and RNS-E are different navigation generations and should not automatically be treated as identical units.

If your navigation system is identified as RNS-D, provide the identification information from that exact unit.

RNS-D vs RNS-E Navigation Plus

The terms can sometimes cause confusion.

RNS-D and RNS-E are different navigation-system generations.

Although both may be described by customers as Audi Navigation Plus systems, they may use different:

• Hardware
• Audi part numbers
• Interfaces
• Navigation media
• Security procedures

Always identify whether your unit is RNS-D, RNS-E, or another Audi navigation system before ordering.

Audi Navigation Plus Radio Code After Battery Replacement

Battery replacement interrupts electrical power to vehicle electronics.

Depending on the exact navigation unit and vehicle configuration, a compatible system may request security verification after power is restored.

If your Navigation Plus system worked normally before battery replacement but now displays a PIN request, check the exact security message.

If it is a normal numerical anti-theft code-entry screen, locate the required radio identification information.

Avoid repeatedly entering random PIN numbers.

Audi Navigation Plus Code After Battery Disconnect

Battery power may also be disconnected during:

• Battery maintenance
• Alternator repairs
• Starter repairs
• Electrical diagnostics
• Wiring work
• Dashboard repairs
• Navigation-unit removal
• Accessory installation

After power is restored, check the Navigation Plus display.

If a normal numerical security-code request appears, the correct PIN information may be required.

Audi Navigation Plus Code After a Dead Battery

A completely discharged battery can cause a full electrical power interruption.

After the battery is charged or replaced, a compatible factory navigation unit may restart and request security verification.

Do not repeatedly try combinations such as:

• 0000
• 1111
• 1234
• 9999
• Vehicle model year

Instead, identify the exact unit and locate its serial information.

Audi Navigation Plus Replacement Radio Code

A replacement navigation unit has its own identification information.

If another Audi Navigation Plus unit has been installed in the vehicle, use the serial number and identification details from the replacement unit currently installed.

Do not automatically use information associated with the original factory unit.

This is particularly important when installing a used navigation system purchased from another vehicle.

Used Audi Navigation Plus Radio Code

Used factory Audi navigation systems are often installed when an original unit fails or as part of an upgrade.

A used unit may previously have been installed in another vehicle.

After installation, security verification may be requested.

If the navigation system displays a normal numerical anti-theft PIN request, our service may be suitable for a compatible unit.

If another message appears involving:

• Component Protection
• Authentication
• Vehicle pairing
• Configuration
• VIN-related security
• Module programming

contact us before ordering.

Audi Navigation Plus SAFE Mode

Some compatible Audi systems may display SAFE or another security state when an anti-theft PIN is required or after incorrect code attempts.

If several incorrect codes have already been entered, stop guessing.

Repeated incorrect attempts may place certain units into a temporary lockout or waiting state.

Our service can provide security-code information for compatible units, but it does not bypass built-in radio lockout timers.

Audi Navigation Plus vs Audi Concert

Audi Navigation Plus and Audi Concert are different systems.

Audi Concert is primarily a factory audio-system family.

Navigation Plus includes factory navigation functionality.

If your unit is identified as Concert, use the appropriate Concert service.

If it is a navigation system, identify the exact Navigation Plus hardware before ordering.

Audi Navigation Plus vs Audi Symphony

Audi Symphony is another factory audio-system family.

Symphony radios and Navigation Plus systems may appear in similar Audi vehicle generations but should not automatically be treated as the same equipment.

Always use the identification information from the actual unit.

Audi Navigation Plus vs Audi MMI

Audi Navigation Plus and Audi MMI should not automatically be considered the same system.

MMI is a more integrated multimedia architecture used in various Audi vehicles.

Depending on the vehicle and generation, MMI security issues can involve:

• Component Protection
• Vehicle authentication
• Module adaptation
• Configuration
• Programming

These procedures are different from a standard numerical Navigation Plus radio PIN.

Audi Navigation Plus Component Protection vs Radio Code

This distinction is important.

A normal radio code is typically a numerical anti-theft PIN used by compatible units.

Component Protection is a separate Audi/VW Group security procedure used on certain electronic modules.

A standard Navigation Plus radio code does not remove Component Protection.

If your system displays:

• Component Protection
• Component protection active
• Restricted functionality
• Vehicle authentication
• Module adaptation required

our standard serial-number-based radio-code service may not be the correct solution.

Avoid Guessing Your Audi Navigation Plus Code

Do not repeatedly enter random PIN numbers.

Common guesses such as:

• 0000
• 1111
• 1234
• 9999
• Vehicle production year

are not a reliable way to unlock a factory navigation unit.

Incorrect attempts may also cause a temporary lockout on some systems.

The better approach is to identify the exact unit and use the correct serial information.

Audi Navigation Plus Serial Number vs Vehicle VIN

The navigation-unit serial number and vehicle VIN are different identifiers.

The VIN identifies the vehicle.

The AUZ or other radio serial information identifies the individual navigation unit.

If our service requests the radio serial number, provide the identification from the actual Navigation Plus system.

Do not substitute the vehicle VIN for the requested serial number.

Audi Navigation Plus Radio Code by VIN

Customers sometimes search for an Audi Navigation Plus code by VIN.

Our standard service is based on identification information from the radio or navigation unit itself.

If the service requests an AUZ serial number, provide the actual radio serial.

This is a serial-number-based radio-code service, not VIN decoding.

Audi Navigation Plus Code After Retrofit

Factory navigation systems are sometimes retrofitted into vehicles that originally had another Audi radio.

If a Navigation Plus unit has been retrofitted, use the identification information from the navigation unit itself.

Do not use serial information from the original radio that was removed from the vehicle.

If the retrofit produces a configuration or vehicle-integration problem rather than a normal numerical PIN request, contact us before ordering.

Audi Navigation Plus Code After Radio Swap

If a Navigation Plus unit has been moved from one vehicle to another, it may request security verification.

Use the serial information from the unit currently installed.

A normal PIN request is different from:

• Vehicle coding
• Module adaptation
• Component Protection
• Configuration
• Programming

Our standard service provides security-code information only for compatible radio-code situations.

Which Audi Models Use Navigation Plus?

Audi Navigation Plus systems have appeared in different Audi vehicle models and generations.

Depending on year, market, and factory equipment, compatible systems may be encountered in vehicles such as:

• Audi A3
• Audi A4
• Audi A5
• Audi A6
• Audi TT
• Audi S4
• Other Audi models

However, the vehicle model alone does not confirm the exact Navigation Plus hardware.

Always identify the actual unit.

Audi A3 Navigation Plus Radio Code

Certain Audi A3 vehicles may use factory Navigation Plus systems.

If your Audi A3 navigation unit displays a normal numerical anti-theft PIN request, identify the exact system and locate the AUZ serial information before ordering.

Audi A4 Navigation Plus Radio Code

Audi A4 vehicles have used different factory navigation systems across several generations.

If your Audi A4 Navigation Plus system asks for a security PIN, confirm whether the unit is RNS-D, RNS-E, or another system.

Audi A6 Navigation Plus Radio Code

Certain Audi A6 vehicles may also use factory Navigation Plus systems.

The exact navigation architecture varies by vehicle generation and equipment.

Always check the actual unit before ordering.

Audi TT Navigation Plus Radio Code

Audi TT models have also been offered with factory navigation systems.

If your Audi TT Navigation Plus system requests a normal numerical security PIN, identify the exact unit and serial information before placing your order.

Why Exact Audi Navigation Plus Identification Matters

Audi used different navigation hardware across various generations.

Two systems may both be described as Navigation Plus while using different:

• Hardware
• Audi part numbers
• Interfaces
• Manufacturers
• Navigation architecture
• Security procedures

Before ordering, verify:

• Exact navigation-system identification
• Complete AUZ serial number
• Audi part number if requested
• RNS-D or RNS-E designation where applicable
