[Q] GPS Satellites can't lock over PRN Number 10

Hello There,

I have buy an Android 4.0.4 Car-Radio System over Ebay.

When I put the Sygic Navigation software of play store, the software
often found no GPS signal. Then I put the GPS software test. I am not so
Used to satellites green PRN or yellow will notice. They are all grey. I have
a new antenna buy, bought with the same result. I have a lot of A-GPS software
tried like GPS Faster, bring you anything either. If in the sky in Germany with satellites
just a higher number like PRN 10 are not can i Navigation anymore. The pictures with I am
too different from all recorded days. There is something wrong, only the programs 1-10 PRN
used to be. The PRN is also funny is that at the location. Youre are my last rescue.

Thank you, Marcel
