It's a test unit for my employer, so it didn't cost me anything. downside is I don't get to keep it...Yes, how much did it set you back?
The database is on the DVD-ROM supplied with the radio. You need to keep the DVD in the radio while navigation is active; thus it's best to also get the in-dash changer. If you don't you won't be able to play CDs while using navigation (though AM/FM and satellite radio will still play.)Also, are the maps stored in memory? Internal DVD? external DVD?
Yep... that's kind of the pointCan you punch in a destination and get directions?
There's a small (1.5" x 1.5") puck antenna which you have to mount somewhere in the car, either under the rear package shelf trim or under the dash top panel. When the map is on the display, it'll show your current position and follow as you drive.Does it have some sort of GPS system to show you exactly where you are?
