Navigation Problems: Troubleshooting & Solutions

Hi,
I installed the large VW navigation system in my Polo TDI, which was manufactured in 02/00.
The kit is from a Golf IV. The location determination...
It works, but the map doesn't update while driving.
The following error is stored in the navigation system: 00867 ABS connection error.
No signal. The following error code is stored in the radio: 01044, Control unit.
Incorrectly coded. I have checked the connection to the ABS, and it is okay.
Could it be that my ABS is not suitable for navigation?
The larger navigation system is not offered as an option, but the smaller one is.
The navigation system does not require an ABS signal.

Best regards,
Gunnar.
