does vag-com communicate with the radio's fitted to the 2001 octavia, as i have a fault with the panel illumination and the radio does not turn off when the ignition key is removed.

Sounds more like a s-contact fault, is it a Symphony head unit?

what's s-contact fault, i've replaced the front panel from another radio that was in the vehicle previously, which had a working panel.

sorry, yes it's a symphony head unit

Whats the display fault?

display does not illuminate, when vehicle lights are switch on, and unit does not switch off when ignition key is removed.

The original radio fitted to the vehicle when i bought it a month ago, would not play cd's, the skoda dealer said it was the wiring at fault in the boot, at the changer, this was checked by a local skoda dealer and no fault could be found, they then tried a new head unit to confirm their diagnosis.

The selling dealer was contacted by them to confirm that a new head unit was required, they supplied me with a second hand unit from another vehicle, which does everything it's supposed to do apart from the two remaining faults, nether of which the original had, so I swapped the front panel over from the radio that illuminated, still no joy, after searching the forums i came across a thread about radio software and what could be done via vag-com, but if you know where the fault lies i would be very greatful for some advise ashow to repair it.

regards

Turning off when the ignition key is removed is a setting within the head unit which is modifyable from the head unit. It doesnt need VAG-COM

VAGCOM was needed to sort this on mine a search should find the thread with details of how this was done.

Just found the info, the radio soft coding needs to be set to 00403 which is the code for CD changer, ignition operation and panel illumination.

What about the fuse. The symptoms suggest to me that the switched live isnt being detected.

I had the exact same symptoms as did Dougal and in both cases it was the soft coding on the radio.
