That's the 2G Nav unit.. Backup copies of the discs are available on the internet, though obviously you would still need to buy the original from Audi to have the proper licences, and remain legal and all that stuff *ahem*

If you get TV audio, then sounds like you have a DVB tuner, have you tested it without the engine running, if I remember rightly, my PF had an issue where the speed limiter had been set to 0 initially, so it wouldn't show TV if the car was running. There are plenty of tools out there to turn on TV in Motion, though you need VCDS.
