Thank you, that's right for the internal receiver.
Now I've got another problem: I cannot see the sat bar during navigation (I can see the bar but it's empty - no sats locked, even if TT is working right) and I cannot see locked sats in GPS status menu.........
Moreover, when I select a destination if I press "C" letter (only C, with other letters everything is ok) TT stops working and I must reset it.
Can you help me please?
My TT version is 7.450.9028
