It has been sitting in the box since I traded my VW in many years ago. Now the circle is coming around, and my son has a VW GTI as his first car. He was thinking of upgrading the factory stereo to something with BT. 

Would my AVIC be a decent install, or is it too outdated to use? I never got into the hacking or modding of it, and I don't even know what version of software it has installed.
