Hi my stat nav is being sent away for a third time to Alpine as I was given a European Sat Nav CD with the car, then was given a CD for a newer model of Sat Nav which got stuck in drive sent away again and Got the correct Sat Nav CD worked for one day and crashed again not being able to eject CD went to get fixed at Alpine again and came back again not working
So have had the car for nine months wih no Sat Nav and two 1/2 months with no radio/cd either!!
