My girlfriend just got an 04 IST as her new daily driver. The car itself is great, my only problem is that the stereo doesn't play any music etc at all. It is stuck on the G-book screen. and pressing any of the buttons doesn't help, or change anything.

Any ideas? For now all I want to do is make it useable with a band expander. later on down the track we will probably replace it with something else. I had seen people have had a bit of success recently changing some other toyota stereos of this era to english, and getting navigation working etc so thought there might be someone who knows whats up.
This is whats behind the screen:

The car also has this crazy thing too:

From what I can tell that is just a voice audio navigation system, so i was thinking of just pulling that out.
Cheers
