i have a 97 318ti. i want to put in a aftermarket radio. the thing i am confused on is which adaptor do i need to buy? i am pretty sure that i have the factory amp and all the plugs i see say they will not work. i found this one on ebay and was hoping that somebody will tell me it is correct or not. http://www.ebay.com/itm/70-8590-BMW-...ht_2062wt_1219 thank you frank
That is what I used. Plug it in and follow the wiring wire for wire and you will be good. My OEM BMW amp works and all functions on my after market head unit work too with this pigtail
