Is there any way I can integrate an Aux Jack into the R53? I don't have Sat/Nav, I do have a factory radio. TIA
Yep. You need this. http://www.outmotoring.com/mini-cooper/mini_cooper_auxiliary_input_Ipod_mp3_hookup.html Plugs into the back of radio using the cd changer deck input.
Absolutely, it's what I use. Just use a 1/8 inch stereo mini jack in the headphone jack to the aux/in and you're set. They're like 2 bucks at RadioShack.
Your Mini is suppose to whine, its a R53. It has a supercharger. I would have thought with all the work you did on it you would have noticed.
