vautier 0 Report post Posted November 23, 2023 Just got a 1996 E34, 540i I've tried searching the forums but it's a mess of information and I can't quite find a clear answer The car currently has a Sony Xru550 head unit - i want to replace or modify it so I can have an aux input. Tape to aux sounds a bit crappy. what options are available for me? If there is a head unit that can essentially slot right in, that would be awesome, but I don't mind putting some time into it Quote Share this post Link to post Share on other sites
Eagle 1662 Report post Posted November 23, 2023 Most headunits will work fine with correct wiring adapter (plug and play connects factory wiring to new headunit). Most aftermarket units look out of place imo but i used this one years ago in my Mercedes of same vintage, looked and worked fine - https://www.amazon.com/VDO-Continental-TR7412UB-European-Bluetooth/dp/B08D2R48HZ 1 Quote Share this post Link to post Share on other sites
Neal 543 Report post Posted November 24, 2023 It’s been some time since I’ve seen that Sony model , I think if your not into the cd stacker you can put a Sony J link adapter in place of cd Stacker you’ll get an aux input via the stacker . Would pay to check the connector type before purchasing one. eg https://www.discountcarstereo.com/aai-sony.html 1 Quote Share this post Link to post Share on other sites
