cntrylvr79,
Thanks man. You seem to know your stuff well. Too bad you don't work at the circuit city by me in VA. This will be the 5th time I've had to take it back... Maybe 6. All my reading seems to indicate that I should just shell out the extra $$$ and get the Z1 or try another brand. Maybe I will see if they will let me upgrade to the Z1 and have the other unit removed...
Oh yeah... What else will hooking up the speed sense wire help or do for the unit??? Will it only help my NAV unit be more accurate; like it doesn't seem to know my home address... but it knows the street
