Sat nav problem

[chris sibby]

HELP
Can anyone help, my built in sat nav on my clubman keeps showing about 20 miles from we're iam . I have been told it could be the aerial or the connection to the nav unit. Is this common?

Most in car sat nav I have used have a re calibration like setting in the menu. If the system was receiving a week signal I do not think it would even be 20 mailed off in my experience. When the car is moving does the car move on the map?

Ive had this in the past where Ive switched it on in an area of tall buildings, inner city say and it cant get a clear lock on 3 satellites so gives a location where it was last time it was used, but after driving a short distance it picks up the signal properly and resets itself.
Never had to do a manual reset.

Hi guys thanks for reply, the sat nav system works, it shows me moving as the car moves but it says I am off route all the time between ten and twenty miles. It has had a reboot also borrowed a another DVD route map but still the same.
The map shows me driving in the sea sometimes .

Have you tried pulling the fuse or disconnecting the battery for say 30 minutes? I thought most sat nav systems have re calibration or adjustment settings. Failing all that it could be a sensor or nav computer fault. Some car sat nav systems use data from the car I think. For example satnavs that use speed readings from car road speed sensor.

What model do you have? 1st gen, 2nd gen? Version of satnav.

My 2007 clubman sat nav is doing exactly the same thing. It is about 20 miles from my actual location but seems to move in the right direction.

I have tried removing the battery for 1 hour but that only reset the trip computer and nothing else.

Did you manage to fix this problem ??

I have read the aerial is the problem, but I dont fancy risking £120+vat for the part if that is not the cause.

i had this with my 2003 Cooper S last November, by looking on this forum I narrowed the problem down to a faulty GPS ariel (mounted in the shark fin on the roof). As a replacement ariel from the dealers was well in excess of £100 I ordered a universal magnetic ariel off ebay for around £8 (can be used outside the car too), plugged it into the back of the nav unit under the drivers seat and placed the ariel on the dash. Works a treat and saved a bundle of cash. The square replacement ariel is small and not too noticeable on the dash, the wire I fed through where the dash meets the windscreen and in the channel under the carpet to the nav unit under the seat.
