Comand installation questions


All is well - it powers up and after changing language to English from german it plays CD's tunes in radio and can be controlled from sterring wheel - nice. BUT when I insert the NAVI CD of UK it sits FOREVER (actually 7 hours now!!) on the message 'ACTIVATING NAVIGATION - PLEASE WAIT'.
I have gone to diagnostics (via MUTE 1 and 3 buttons) and checked under INFOS where I find that the GPS SAT shows 0 - I know that really should be showing at least 4 or 5 sats

So I got hold of another Antenna - yes I know have two antennas and still no change.
My question is - am I beginning to realize that the SAT\NAV side of this unit is dead - if so can it be repaired? Any idea of cost? Or am I just doing soemthing wrong?
Any help would be ace.
your comand has a faulty CD drive if it doesn't want to read the (original) nav disc
greetingz,



Any ideas? And if it IS a knackered CD drive, how much is that to replace?
