This is based off a 90 325i without premium system, no amp, no fader. The stock head unit finally gave up the ghost and the speakers were shot. So it was time for a replacement. As much as I liked the base HU I decided to upgrade so I could have a Bluetooth phone system and streaming. I decided on the Blaupunkt Toronto 420BT. The basics: front and rear USB, SD Card, aux in, external mic port, IPod/phone direct control, Pre-amp 4-channel (2 V), and Sub-out. The last two I didn’t really care about but were nice if I decide to further upgrade later. I also bought two sets of Rockford-Fosgate R152-2 component set ups. Total price for everything was around around $280.
Attached is the pdf. of the install to save on bandwidth and it would be easier to print out if you want. I skipped the obvious stuff as it has been covered several times on the forum. Here is the wiring for a base late production e30 wiring is as follows:
