Hi mate, that looks like a nice install... how is it going now? Oh, and I'm looking for a digital tv antenna that works too, but its seems like a lost cause. I've read that the car's shell severely limits the reception, so perhaps an external antenna would work? Or go to analogue?
I've just got the nav working in mine. The install was finished in December, except for a button to turn it on (at the mo I'm turning it on in the boot, then leaving it on standby (wake on usb) for the day while I'm in and out, and then hibernating overnight - works well, and has been for weeks like that). I've used destinator 7 with a gps receiver.
I came across your thread cos I was looking around to see if its possible to use the gps receiver to access satellite TV... yes probably a lost cause but worth a look!
