Decided I'd really like to fit an auxillary port into my car to play stuff from my phone, and I understand the only way to do it and keep the stock stereo (which I want to do) is to install a Connects2 adaptor which connects to the CD multichanger port on the back of the radio?
Question is, does the Connects2 come in just one flavour or are there seperate models for semi-mux and full-mux cars? I'm lead to believe it's the former as I cant find any differences between semi-mux and full-mux factory stereo's but I might be quite wrong...
Any input would be appreciated
