trueog - Thanks for this writeup. Very helpful in understanding this newly-acquired car (2005 W211 E320)...

Among other things, am replacing rear windscreen, so am evaluating repair/replace on the broken sharkfin. GPS Nav essentially works; I have to diagnose further.

With the glass out, I have an opportunity to do this right - to route coax through the correct rubber channels in new window 'encapsulation'.

Importantly: What is the coax on the right side of car connected to, and what would replace it/its function?
