Hey people, I am needing to replace a faulting car stereo in my 90 series and am considering a Polaris double din In-dash multimedia/gps unit with dual mapping. My question is can anyone offer an opinion on the functionality of these units and as I already own a heap of hema maps can I upload them to the unit or read them from an sd card or do I need as suggested by Polaris have them pre install the maps at an additional cost.
Thanx
Mick
