What is a good mp3 HU that also has a front AUX in plug? Also are there any aftermarket HUs that work with the BMW CD changer?

alpine 7894 but discontinued but ebay has them still the alpine has amber and green lights that r switchable... also the alpine 7998 is a good piece..... actually u can buy a kenwood or a sony get an adaptor to trick the headunit that the cd changer is on and that becomes ur new input... rockford fosgate also has inputs and clarion.... its all about how much money u wanna spend and the features u want

i would go with a rockford headunit but ou wont be able to use your cd changer no more .that sucks but they have the cleanest rca,s and heads you can get today i think atleast in my mind .. pus you can get them with 5 volt preouts not even alpine does that and now rockford makes a headunit with 8 volt preouts but no speaker amp on it you have to have an amp to run your speakers .

Eclipse also makes head units with 8v preouts, and some of the newer high end models are boasting 16v. I just put in an Eclipse 8051, now replaced with the 8061. It's a non-powered unit for use with a systems amp. It has 8v preout, an auxillary input, seperate sub control, and it sounds great even when running with the stock amp, although I'm about to replace this.
