Hello,

I try to be short with my question, I have a nav mk4 system with v28 on it.
it workt realy good until two day ago. no signal so the nav has lost his way.

i read a lot of troubles here in this forum and i have tried the next things.

disconnect the battery for 5 minutes, after that i switched te key in pos. 1 and wait 20 minutes, i lookt in the hidden menu.

the next things i saw.
1 I only had 2 S/N numbers >0 but not >2 so i thing this is to low.
sometimes i had no s/n numbers. the prn number where change-ing
2 Almanac is NO
3 Rec-sat: Recerr
4 Pos-src: 0
5 Pdop/Hdop/Vdop: 0.0/0.0/0.0
6 GPS status: Reception interfac
7 visible satalites: 8????

Can some one tell me what's going on??
