Hi guys.
I have a 2007 range rover vogue and I'm having sat nav problems
firstly I had a message come up saying disc error
I bought a new Map DVD and it made no difference.
I then bought a DVD unit and then it came back to life

but I have no GPS signal
everything else works I can put in a post code and its fine, if I calibrate the unit and manually put in my position it works fine it will follow the road using its on board gyo.
but no GPS

so I bought a brand new GPS Ariel and installed this onto the roof.
now some times it work and sometimes it doesn't

I have gone into the service mode and it looks like it is seeing the satellites but its not always storing the information

before I put my hand into my pocket yet again, has anyone else had this problem

thanks in advance

Stop throwing money at it and take it to a dealer

That might be the next step
