Navigation Question 2008 GC RER radio
I just bought a used 2008 Grand Cherokee with the MiGig RER navigation radio. I have looked at the manual and played with the unit a little, but can not find out if you car run the map display without the radio being on. I do not use the radio that much, but would like for the map to come up when I start the car without having to use the radio. Someone with a good knowledge of this radio may be able to head me in the right direction. The manual said something about standby mode but I could not figure how that even works.
