I HAVE HAD THIS PROBLEM....

I feel for you i hated that fucking issue. There is Nothing i knew to do except find the latest software updates and eventually i just decided to sell my z series GPS and get a F90BT.

Im sorry.

This could be caused by the location of your GPS antenna. Where did you put it?

especialy if you additionaly do not have your Vss connected...

I hooked up my vss and no pulse what so ever , I actually paid an authorized shop to do it to .It's currently at the repair center and will probably co$t me an arm and a leg to fix, oh well. I'm thinking about buying a RevoSys X300 Double DIN CarPC , anyone know if they are any good?

Question to lludacrisboy :

Have you connect the VSS before you gave up ?

i located the gps antenna on the roof with a tiny slop on the scion tc 2007

didn't connet the VSS yet, i have to look for the wire.

Mine did that exact thing.

I had to reset the 3D calibration. all better now aside from the MPH screen in the Maps area doesn't work I'm just happy I'm not drifting everywhere I go now.

For reference my GPS ant is in my back window. 02 Passat.
