Recently had the satnav retrofit installed in the car by another fourm user. He did a great job and it works fine.

EXCEPT!!

The nav unit keeps veering away from the road when I turn a corner and takes ages to find the road again, sometimes making me miss turnings etc.

Last night I set off from edinburgh to my home (about an hour away) and we were half an hour down the road before it realised what road we were on!!

any ideas? I have positioned the antenaa on the window ledge because my car is an estate.

please help, as I`m away round Europe on Thursday and I don`t really want to get lost!!

 

Are the maps uptodate?
New by-passes and road modifications can confuse them.

 

have you installed an original Jaguar Sat nav ? if so when you eject the disc what year is the disc it's runnin on ?
but sayin that .... it should find you quicker than half an hour !
