Anyone? I'm sure lots of you installed it yourself... Are there some screws I can remove from the front of the unit? The side?

I think there's actually a MB under dash GPS antenna for the older SL models. But you should have a GPS/cellular antenna on your roof towards the back, can't you use that one? You might have to order splitter or something to make it work.

My Avic-Z1 was installed a long while ago by an installer, but I'm thinking about updating the map and do the double grounding bypass. I really don't want to go back to the installer to do that since they charge a lot, is there an easy way to just slide the unit out and do the grounding wires without removing the whole thing? BTW, the unit is installed in a MB ML320.
