Hi all , I have a bit of an issue so am after some help if anyone can help please ?
Basically I had the standard HU out to begin running some wiring for a parrot , popped the HU back in and it appears to be dead :-( , I have replaced the fuse in the back if the unit , and tried pulling fuses 7+43 I think it was as a few searches mentioned this, but no joy, it does not display anything or make any sound , I also tried restarting it by holding eject and power for 20 seconds but no joy so help please if possible ?
My car is a standard e90 318D lci with the basic hifi professional HU if it matters, and I have not altered or cut any standard wiring at all ,and when I have the lights on the HU lights still come on, but no display or anything, thanks again .

You might have run your battery down working on the car.
If you have an IBS system it can turn some stuff off like
the radio in order to conserve whats left of the battery .

a code read might tell you something.
Or verify the harness is getting power with a Voltmeter.

Well that was a pain , checked pretty much all the fuses related to the radio, and all ok , have checked the voltage and definitely a 12v permanent and a switched going to the HU, I was debating doing the IBS reset I have read about where you take the negative terminal off the car battery for a bit and it apparently resets , has anyone heard of or done this and knows if anything to beware of ? Any thoughts appreciated ,cheers .

Did you back out of the install?
To retrace your steps?

I wasn't going for the full install matey, I am pushed for time,so messing with the car I have to do in stages,so I had only gone for running the wiring to the screen ,and mic , I had not ventured far enough to connect it up, that's why I am baffled, I checked the wiring to make sure I had not somehow snagged anything,which I hadn't , so it's a mystery to me , I think I might have to see if I can find someone local to see if any error codes are showing , I will post back when I have , thanks :-) ,Den .
