Today I noticed the 'gps' logo on the nav screen was crossed out with a red line. I've had that before, but only in underground car parks or when a significant amount of the sky is blocked by moutains or buildings. The sat nav still seemed to opperate normally. It knew where I was, rotated and moved the map as I drove and was able to provide the normal turn-by-turn directions.

I tried to check the issue with the iid, but I didn't get much. One strange code was UO248-87(2F). Google wasn't helpful with this. Iid didn't seem to find much. Is there something specific to look for?

So, troubleshooting so far:
1. 'clear all faults' using the iid didn't fix the problem.
2. leaving the car and returning later to see if the computers reset. Nope. Still the same.

Any ideas? I don't like the gps error line, but, with the maps so out of date, I also don't want to throw much money at fixing it when an external gps is a lot better (though astetically displeasing).

Yes, I did check and the iid have the latest firmware.

Much thanks in advance.

Hi RR2008HSE - please take a look at this thread: http://www.fullfatrr.com/forum/topic17777.html

I had the same symptoms in our car, and ended up with buying a gps from according to the specs in the thread above. Easy DIY fix - GPS working fine now.

THANK YOU, ERIC. That is a great help. I'll print that out.

As an update: I didn't use the car the next day. After a 24 hrs rest, when I started the car, it had lost its location (it seems the wading depth is good enough for the mid-Pacific, according to the map!), but the gps error icon had disappeared. Within a minute, the car had determined it's correct location and the gps has been operating normally since. PHEW. Long may it continue.
