So, I've run into what is probably a familiar problem to you guys...installed a new head unit with the factory Harman Kardon amp and speakers, and now I have no sound. I've been told this is because my head unit doesn't talk to the amp, but I'm not too sure what to do about it. I apologize in advance if there is already a thread about this, after looking I didn't see one addressing this particular problem...

 

Sorry, I don't have any help for you but...you've posted this in the 2nd gen forum and if it's an R53 you have, you should try posting in the 1st gen forum.

 

Oh....whoops. Sorry bout that...

 

The HK HU & AMP must exchange data signals to work. Unless you're an electronics wiz. Been there done that (BTDT) after the HK AMP kept failing in my 03 R53. When I bought my 06 R53 I ordered a normal head unit, bought an aftermarket amp & sub (Less than HK system) and wow! HK System was a waist of $$. Sorry for Forum error.

 

To use an aftermarket headunit with the HK system, you'll need an HK Enabler: http://www.newministuff.com/new/shop...uctshow&id=116

Ian Cull (GBMINI) developed the circuit and wrote about it in his blog: http://www.gbmini.net/wp/2004/06/min...roductionized/
