Well as I am bereft of a centre vent at the moment, I thought I'd finally fit that ICM3 head unit I've had in the garage for 2 or 3 years, but never seen working.
It went in very easily, and I was worried the screen might be knackered or missing loads of pixels, but no, it works and all looks good.
At first when I turned the ignition on there was no display on the SiD, but soon after it appeared as normal.
Someone else who had put an ICM3 head unit in their car to replace an ICM1 unit, said it worked but then the radio would cut out every 10 minutes or so, and he needed Tech2 to tell the car/audio system what features were/were not on the car, and then it worked without any issues.
So I went out for a run to see if I had the same issue, and I don't. The radio behaved itself throughout. However, if I select CD (screen says CDX), it says no CD is present, even though it is.
The aux input does work though, thankfully.
When I got back I noticed the rear park assist didn't seem to be working, so I looked through the menus on the SiD but it isn't there at all.
So it seems I will need a little bit of Tech2 intervention after all.
The rear parking sensors were one of the first upgrades I did on the car after I got it 5 years back, and I got a specialist to fit it for me and do all the Tech2 stuff.
I was wondering whether it was worth getting the 6 CD changer as another simple upgrade (are the changers less reliable than the single CD?), and would the ICM3 recognise it without Tech2?
