How can you tell what firmware version you have?
On some units you can hold down the setup button for about 10 seconds and it gives you a hidden menu that tells you about version info etc. If you want to check if you have the latest version, the easiest thing to do is try putting in an SD card that is MORE than 2gb. The latest FW is the only one that will accept anything greater than 2gb.
Other than that - the sticker on the back of the unit tells you its original version.

The required bits are the GPS Antena and the VW Code Card. Optional extras are the V5 Map Disk, and the latest Firmware (probably required for the climate control to work), and a shot of a VagCom to get it coded to your MFD / steering controls.
Judging by this... fitting should take you about 10 mins - even if you don't know the first thing about car audio!
