i have a 04 basic and was wondering if the bose HU (with the DC changer, tape, etc) will fit (to replace) the HU of the basic 04 (which has the FM/AM radio, 1 CD player). there were some HU in eBay and was considering to get one.

is this a good idea? or what do you recommend to replace the HU of the basic 04?

thanks in advance
