Would be very grateful for any guidance - help with my problem

Have a 2003 (2004 model) 996 C2 man with pcm2 in the UK

When we were on hols in Somerset i set the sat nav to get us home, within a few miles the displays kept on comming up with "off road"

Thought it was just a glitch, took the satnav cd out, left the car for two weeks. Went to check the car last Sunday and its still the same, the car still thinks its in Somerset - according to the map, I can put a destination in and the car calculates it as if its still in Somerset.

Have tried 148 to reset, then I thought i would disconnect the battery, so undid the negative lead and tha alarm went off, put the lead back on and the alarm stopped, by this time I was fed up and thought I will reset the clock and have a drink, reset the clock but now the time does not change.

The clock in the dash is there as well as the one in the Pcm but the the displays do not change!

Any advice would be great, my blood pressure is off the scales with my pride and joy not working

Many thanks

Jonathan

dead sat antenna is one possible explanation. clock in 2003 996 is set automatically once nav picks up satellites (there is a TSB about it and how to set it up). if antenna is dead=no satellites=no clock

Hi

SA321 - spot on many thanks.

Have checked the status of the satnav and no satellites are being found.

So whats the next stage, I know I need to take it to a high point, lock the car and leave for 5 - 10 mins but what next? Do I start the car and press 1 4 8 or do i just turn the ignition on or just unlock the the car or what?

If this does not work am I safe to assune the satnav antenna is broken?

Any polite advice would be great, becoming obsessed with this problem

Many thanks in advance

if you have car outside for 10-15 min and see no satellites then your antenna is likely gone. you can try to take it out and replace yourself (gbp80) or take it do a dealer. there is a chance that if you buy antenna yourself it may turn out that there is more serious problem like the PCM itself so you are 80gbp out of pocket
