This was a CD burned by myself from the link given in this thread. Burned with 1x to non-branded disk with ImgBurn in mode1.

It seems that also GPS receiver has new software after this upgrade. Is that a normal condition?

I would still need some advice how to proceed. As said before, problem occured already after first reboot of system, so nothing has physically changed in the car, otherwise I would expect to look for loosen antenna cable etc.

How to get the almanac force read to GPS receiver, maybe?
