Hi all,

Acquired a MK4 sat nav unit and fitted it last night. Like a Muppet, thought the gps aerial cable unscrewed (it doesn't you just pull it off). So I kept unscrewing and ended up with a very twisted cable, eventually felt like the innards of the cable gave.

Noticed this morning, the car thinks I'm 197 miles away from where I am. Presumably the address of the previous owner of the nav unit!

How do I confirm I've broken the gps cable? Is there a hidden menu showing the signal details? 2004 Vogue TD6 - Remapped

Just to answer my own question, found the relevant hidden menu. Go into settings, then hold the menu button down for 10 seconds. Select sensor check. Showed communication with 6 GPS satellites and a location lock. Exit that and all is well 👍 2004 Vogue TD6 - Remapped
