Got myself a Harman Kardon Drive and Play kit a while back, but I'm getting a little pee'd off with the crackle that I get through the FM transmission (despite having it wired on to my aerial).

I have a CCR2006 headunit which I don't want to replace, but as most people know, it can't take an aux input.

Just wondering what my options are for getting decent audio quality from my ipod...

I've been wondering if it's possible to pick up a seperate amp which will take speaker input from my headunit and RCA input from the HK kit. I'd need a way of switching between the 2 easily (unless it could automatically detect an RCA signal and use it when the HK kit was on). I'd also need a way of controlling the output level of the amp easily, as the HK kit doesn't have a volume feature....

Anyone got any ideas for me? I'm a former sound engineer so no stranger to complicated audio installs, just never really done too much in the car!
