Overall I'm pleased with my D2, this is the first aftermarket head unit I've ever purchased. It intergrates into my vehicle very well, looks like OEM almost with the LED being green, hints of chrome trim. I really like the vehicle dynamics, XM is very nice with the GEX-p920. However, it can't tell me how to get home. It knows my address but it tells me to go past my driveway by ~2 tenths of a mile and turn right and my house is on the left.
I tried it going to work the other night and it was spot on, I followed the directions right to our security office out front door. My house is out in the country, could that confuse it or something. I don't expect it to direct me to my front door, but it should at least tell me to turn left instead of right after I've went past my drive way 2 tenths of a mile.
