Accessing the Setup Menu on RNS 510 head units with firmware version 2660 / 2662 / 2664 / 2666 / 2668

Firmware versions 2660 / 2662 / 2664 / 2666 / 2668 access to the Setup/Test Menu.

Option 1 – Vagcom/VCDS access

Using Vagcom/VCDS open Channel 37 – Navigation, go into adaption and change channel 50 to 1 (will be 0).

To enter the test/setup mode when the RNS 510 is operating press and hold the setup button, keep holding it when the radio menu appears and shortly after the test menu appears . I had to reboot my unit after coding it but it may be possible a power cycle is enough.

Option 2 – Edit the firmware image (not sure if this allows one off access or permanent access at this stage????)

To enable this edit a file on the firmware DVD before updating.

  • WA\EURPQTO.WSH for Volkswagen or
  • WA\EURSKHDD.WSH for Skoda

Find these lines

# Testmode: NOT active
SetRegDataHex(0x21,"00",0x0,0x1,0x1)

and replace with

# Testmode: NOT active
SetRegDataHex(0x21,"01",0x0,0x1,0x1)

Check the file length after editing otherwise the firmware update will fail.
