Sat Nav issues

Hi all. A couple of folk have helped me recently with engine issues now I am having issues with the sat nav. When we done the engine work my friend disconnected the battery. I didn't know of any procedure required to maintain function on sat nav unit ie: power the unit down first.

So. After reconnection of battery I noticed no change with radio function or cd/ changer. But. After 20 mins of sat nav guidance it stops guidance and goes to please wait screen ? Then sometime the oem like windows 98 screen ?

Any ideas. It goes back to normal when restart car ??

Hmmmm
Thanks for any ideas in advance. I'm going to try the fuses out and in 41 and 7 I believe. Would it be worth just reinstalling the map and camera disc ? Could it of just herped the durp ?

I had this issue develop on my nav as well after several power outages and a new battery. As strange as it sounds, I "found" a newer USA map and since I've put it in the problem hasn't happened once.

I think you can probably find it as well if you know where to look.

EDIT: I've noticed you're in the UK, same procedure should apply.

Tests

Thanks for the response.
So far I took the disc out of the player. Then done the fuse trick
41 and 7. Had a play with some other fuses.

Where the 3 bank of 50 amp fuses that control the electric fan
The secondary air pump and another thing not on my car at all so I've forgotten. So. I had a fuse in the electric fan slot........ I have an automatic ? Therefore the reading I got from my diag tool about secondary air pump not active may be for that exact reason. So. Swooped out the electric fan slot and into the secondary air pump. Yet to do diag cause it's freezing lol. But think it's a no brainer.
