gps problem on 2005 pacifica
i have a 2005 pacifica touring with gps. the gpssystem has been a little inacurate, it would shows me routes that I am not on and it take a while sometime to re-route a new route. when I make a turn the arrow continue staigh as I didn't turn. and it doesn't help since I can miss my exit by the time it come back to my location.
at first Ithough it was do to the old software but just purchase the new 2008 dvd for update and itsgiving me the same problem. I should of spend the money in getting me a portable gps instead if I knew it wouldn't work.
can someone help? is there any setup step I need to do for the gps to be more acurate? or maybe the gps antenna is not getting the reception it should be getting? where is the antenna located anyway. ?
thanks for the help.
