Thanks Russ. I might need to replace my dash stereo because it doesn't have auxiliary audio inputs. It does have Sirius capability, but I opted for a portable XM receiver. I currently plug a Creative Nomad Jukebox 3 into the Sony coach audio system, both when parked and when driving down the road. The Nomad is bigger/bulkier than the iPod but, at the time I bought it, Apple didn't have good CD ripping software to run on PC.
Did your Bose come with the coach, or was it added later? I have a "spare" Bose Lifestyle system I removed from the family room at the house we sold recently and was thinking about installing it in the coach to replace the (IMO) inferior factory Sony system. On my to-do list for some time has been a complete re-wire of the A-V systems in the coach, but so far I've not managed to get around to it.
