Is this an Audi Delta CC head unit?

I am going from memory but I think there's a 5A fuse next to plug II and III.

Check this post.

The power comes into the top plug III, on the Delta there is also power to pin 3 plug III, newer Concerts have K-line on that pin instead so it needs to be clipped if it's not a Delta.

I have experienced similar problems with my radio. Sometimes when I turn it on, the SAFE signal appears. Occasionally, when I turn it on I get nothing at all. Usually when that happens, it will work after I restart the car. I haven't pulled the unit out of the dash as I don't have the appropriate tool/key to do so without damaging something. Anybody know where I can get the tools/keys?

Thank you.

E bay or you can make homemade ones with a dremel. I have heard Walmart has them, I haven't verify that.

You can make them out of folder hangers or hack-saw blades.

Make sure you inset them the correct way, as you can really mess things up.

i been waiting all this time for my radio harness (to connect a aftermarket radio) to come in and it did. turns out after i connected everything that radio won't turn on....so my stock radio wasn't broken. i checked all the fuses and they are all good. why isn't my radio getting any power still???? these long quiet rides suck!!

You need to check what power is missing, there is constant power on plug III pin 7 and switched power on pin 4. There is also power on plug III pin 3 on the 96-98.5 cars. Cut that out in the aftermarket harness if it's there.

There are a couple of signals that come out of the head unit for the antenna amp and external amp if you have one. Wires are blue and blue/ white on aftermarket looms. Sometimes a problem with the amp control will take everything down.

Also make sure you have ground on plug III pin 8 without that nothing works.

If all else fails you could buy an inline fuse and run power direct from 75X under the steering wheel.

Not specifically part of this problem but if your car is Bose, it's a little more complicated to wire, hopefully you got the extra harness with RCAs if that's what is going on
