where did you mount the antenna?

I'm a bit lost when you say about the DVD locating as a dvd doesn't need satellites.

I've found the best place the satnav antenna is on the left wing from inside the car (try right wing for LHD)

failing that what the roof?

I have the antenna behind the central mirror
That's my question.The only part that is responsible for satellites's locate is the antenna?There is nothing else into the box of dvd that needs a gps program to work.Is that right?
The antenna module has the antenna+receiver?In this case the whole job about satellites and locate them become from this module and the dvd have only to run the gps program (igo,sygic etc)?
i try to understand in which part  is the problem.Is a fault of antenna module or there is problem into the box of dvd?
