You may find that the ignition supply you have to the HU disappears whilst the engine is cranking. May need to be a permanent ign supply (if you know what I mean!).

cheers but how do i get a permanent supply?

It'l be worth checking with a multimeter first to see if that is the problem.

If it is, then check other wires that are available to the radio, failing that, you may have to take a feed direct from the ignition.

There are loads of others with more experience of fitting corsas on here, I'm just telling you what I've seen in the past (I fit radio comms, tracking & SatNav in Ambulances!)

mate,look at the wires on the connector block on the back of ur headunit. Switch the yellow and red ones around. they should have a split in the middle,so u can swap them around. that should solve ur problem. its all in the manual,take a look in there if u dont know what im on about.

YES!! This will work on kenwood... and maybe with other source unit... :wink:
