Used an iidtool for the first time today to clear down a load of errors and since then the touchscreen starts up with the car, radio comes on, runs for 5 seconds or so then turns off. No lights on the unit and can’t be turned back in again unless you restart the car (same thing happens again).
Any ideas?

No one seen this before? I’ve just seen it flash up A/V off when it went off if that helps at all?

Check all the fibre optic connections to the various modules in the left rear compartment - I had similar symptoms and discovered one connection wasn’t secure.

To close this off. This sprung back into life after unplugging the battery for a while and plugging in back in again.
