2. How to change languages in your mk3/mk4 and the OBC

Send following HEX-string to your car

3F 09 3B 07 01 FF 80 81 83 00 cs

The relevant bytes are in bold. The logic behind the string is:


first Bit: Languages D=0, GB=1, US=2, IT=3, ES=4, JP=5, FR=6
second Bit: male=0 , female=8

example: female GB / Female IT / male FR results in 81 83 06

!!! Warning !!!
After you have send the command to the car you will get a message on your monitor to insert a Firmware disc for loading the proper languages (V28 will do just fine). After the loading the system reboots. Now you will have different languages in the Check Control and the set menu from you nav system.



3. How to recode MK3/MK4 from monochrome to color display

What the dealer has to do:

First connect the GT-1

1. Code ZCS/FA
2. select after sales replacement(retrofit)( i know it isn't, but other wise you can't code the MK4
3. select IKE
4. select language
5. then you have to selet the 3 languages
6. Then on the nav screen you wil see load software. But you can’t see because your Nav still isn’t code for the Monitor. Butt you musst put the V26 in the MK4.
7. after you putt the V26 you have to wait in about 2 minutes the screen wil come, last time it took about 4 minutes.
8. After the succesfull software load , you have to select recode the Navigation computer, an you can code the MK4 to your car.


If you look at steps 1 to 7 IT IS THE SAME as in my second post above!
