Help! Symphony II unit

[ezpraye]

Hi there mates!

Hope I can get some help qiuckly!
I own a audi a4 B6

I have a Symphony II (8E0 035 195 C) CQ-EA1070LA

I have found a new one I wanna buy Symphony (8E0 035 195 P) CQ-EA1270L

What is the difference beetwen C & P and 1070LA & 1270L

Is this compatible with my car

By the way is there a list of the different partnumbers for the Symphony models?

Have seen that there is one list for the RNS-E units
