Ai-Net to something like the PAC icAV2 works well and charges the ipod/iphone including 5V units. If it is for a boat, you should look at the CDA-9886M and MC10 remote.
yea that mc10 remote looks slick. it sure would be nice to have that mounted near the rear deck.
the 9886m looks nice but i really like the ida100m. think it makes a big difference to go with marine eq over car stuff? i dont plan on the radio getting wet or even touching it much, either just set the xm channel and go or control it from an ipod. i guess you never know.
Alpine marine stuff has coated circuit boards and passes salt/fog/UV testing. Marine stuff will work with MC10 and MC1 remotes which allow iPod control from the remote. Non-marine stuff won't. The radios still can not be splashed with water but they will put up with the marine environment better than non-marine stuff. Some brands of marine product (some kenwood and sony models) can be splashed with water and live.
