intercom wth ipod and charger

[gothbiker]

can anybodu advise me which intercom system to buy? I'd like to speak to my wife on the back, listen to my ipod and be able to charge it aswell, and maybe use a mobile phone with it, I've been reading for the past few hours, the best seams to be the autocom, with an ipod mounted in a ram case or box.
any advice will be great, just ended up more confused than anything else!!
thanx dj
