NTG4.5 Map Code

This Head Unit is the longest duration of the NTG series. It can also be reffered to as NTG4.7

How to identify NTG4.5

One of the easiest ways to identify whether your car is NTG4.5 is to use our Car Lookup feature.

Purchase a Map Code

Purchasing a map code has never been easier. Simply follow our guide here. Or follow the form below (after creating your USB)

Region Compatibility

Important Notice for Korea, Southeast Asia, and Japan Vehicles

If your car has a region of Korea, Southeast Asia, or Japan (including imports from these Asian countries), and you want to migrate to a navigation from a different region (such as Africa/Middle East or Europe), you cannot use our service — the update will not work.

Before purchasing a map code, you must:

• Change your head unit's region first by finding a service online, or
• Replace the head unit entirely

Refunds will not be granted for region incompatibility issues if you proceed without addressing the region change first. We provide clear warnings in our code generation dialog and guide pages about this limitation.

Common Problems

Here are some common problems you might encounter when purchasing a map code for your NTG4.5 car.

USB Stick is not valid, even though it is correct

If the car refers to the software update as being through a DVD, just follow the instructions but with the respective USBs required.

This is likely a region error. If you are unsure of your car region, please use our Car Lookup feature to verify your car region.

With NTG4.5, you can change the "DVD Region" to:

• 1 for USA
• 2 for Europe
• 3 for Asia

USB formatting (FAT32)

• Requirement: USB must be formatted as FAT32 for NTG 4.5 units to accept the update.
• If Windows will not let you format large USB drives as FAT32, use the GUIFormat utility.
  • Download GUIFormat: http://ridgecrop.co.uk/guiformat.exe
  • Open the tool, select your USB drive, set Allocation Unit Size to 32768 (32K), leave Volume Label optional, and click Start.

Below is an example configuration for GUIFormat:
