I have a nice system finally, aftermarket radio with backup camera, four speakers two of which are led changing colors and the rear sub woofer. Now the issue is music, radio is out just because I don't like the ads. I can play CD's but have so far been using a USB drive. I have plenty of music on them, over 2,000 but the drawback is selecting the folders which is a hassle while driving. Final straw for me was pulling up at a stop sign and it's playing Macho Man by the Village people. I've spent a lot of time building up my image and scaring little kids, even the occasional teenager and this was a definite negative. I have a number of toys, four motorcycles, two boats, one wife etc., and am looking at an alternative (I'll keep the wife, for now) . I'm thinking the XM radio with Bluetooth would fit the bill, can swap between toys and just have the one sub. Not sure if you need a mounting kit for each toy but will check into that. Anyone else done this?
