GPS signal lost

[Djfab3345]

Hello,

I have a nav system in my mini cooper R53 it worked perfectly yesterday, but today it cannot find my position, so i have disconnected battery for 30 min, go to the secret GPS menu and it is written "RECERR" but when I go to GPS tracking sub-menu i can see all sattelite with ratio moving but SN are between 1.5 and 2.5.

Almanac variable is set to "no", do you think it's possible that the gps cable is a little unplugged or the antenna is shot ?

I will check for cable this weekend because on the mini it's under the passenger seat not very simple to check

So if you have an idea to help me i'am listening

Thank you.
