How did you install the Eonon Unit, did you purchase aeropro cable adapters or cut and splice wiring?
If you do have the VDO Dayton is there still power to the electronics and GPS under the drivers seat?
Are your dash lights still working?
I hope your right.

When I read the first post I was expecting the Nav system to be switch on from the audio system via can-bus.
