To help foster the use of my 2 HT set ups in the house, I got a Tekkeon NavDock to use with my iPod Touch.

It's pretty simple and lets me plug into wherever the party is in the house and play music on the iPod. Comes with RCA cables (decent quality).

The menus show up on the TV screen and there are a couple of screen savers to avoid plasma burn-in. Even shows the album art.

The IR remote is pretty cool and I was able to learn the commands on my MX 850 & 900 remotes. Couple of macros and we're off to the races.
