My bose has given up working on the left side speakers when playing CD's I've already stripped down and re crimped the ribbon a few years back and worked a treat until recently so time for an upgrade. I'm total useless when it comes to electrics and audio so there will be a lot of stupid and basic questions asked attempting this. Its a 04 GT car if that makes any difference   I want a set up that I can use for Music(CD's, blue tooth, wifi?) Sat nav Reversing camera I'd like to keep use
