thanks for all the help crookedtoe, ill look into the diff configurations. My brother also has a C230 and theres a mod that allows u to do an aux in. all it takes is a 3.5mm to the red and white jack and some soldering. I saw it on one of benzworld.org. i saw that you bought that Logjam AUXMB1 already, but if u wanted to maybe sell it on ebay for a profit and try that mod im telling u about, u might be able to make some money
