Seat Ibiza lcd display not working, inc climate control

Hiya,

I've got what I think might turn out to be a rather expensive problem with the display, radio and fan controls

The car outline on the display was flashing 5 times (which in the manual stated that there was a problem with the air con, but it stuill worked, so I stupidly left it) I presume this was the start of the problem.

then I didn't drive the car for a while, leaving the battery to go flat. now its fully charged but the display panel only shows the time (11:28) and nothing else.

the buttons for the fan and air con have also refused to work, so I've had to take the fuse out to stop the fan from blasting out really cold air.

I've had the fuses checked and they're all fine, but that's my limit of techy knowlege I'm afraid!

the worst bit is that I now have to drive in silence, and I'm having to do a long journey from Soton to leeds - I need tunes!

any advice would be most appreciated,
