I'm under the impression that the AUX in won't work with the HK radio. Is that correct?

 

I believ eincorrect.

I believe MINI says it wont work with teh NAV - that has been proven false by members of this board.

search and ye shall find

 

Aux works with or without Nav in cars with or without HK. The only issues regarding Aux compatibility so far is the car must be an '03 or later, and it must not be a cassette headunit. If you want Aux capability in these situations, you have to use an aftermarket solution such as one made by Blitzsafe which uses the input normally reserved for the CD changer. This of course precludes the use of the changer.

I was one of the first to install the Aux in a car equipped with Nav, and was easily able to have the two coexist. There was nothing provided in the instructions at the time to address the Nav option, but it was easy to figure out. I shared it with everyone at this thread.

 

got it installed in mine, I got H/K

very sweet addition, but, don't put it in the glovebox. I put mine in the plasic piece under that whole console thingee. Like a 3 minute install. If it takes any longer, you've done something wrong/the hard way.
