Does LK-7900 w/ GPS need external antenna or is it internal?, and will the external make a good difference in accuracy of location? and can I mount the external antenna inside the dash, up top, close to windshield, so signal only has o come through the glass and a little layer of plastic...
I don't wanna mount it on the roof like the old Garmin external antenna, like a second XM Sat antenna..
RSVP please help the rookie newbie thanks
