Using the keypad to punch up an XM channel.

#3. Satellite radio for me
So, DVD video to keep the kids occupied, navigation to keep my wife, uh, informed, and lastly for me, XM satellite radio. I have to admit, I am an XM fanatic and a self-ordained satellite radio evangelist. I've had XM in my vehicle since the day it became available (actually, I had it a few weeks before it was officially available. Hey, being a trainer for Crutchfield has a few perks!). And though I've used XM on several different receivers, my hands-down favorite is the interface through the IVA-D300. On the 7" LCD, I can display my choice of channel info, artist and song info, or even all three at the same time!

The IVA-D300's XM interface is the best I've ever used.

I also enjoy the multiple forms of channel access. I can tune in stations by presets, by category, and even by a 10-key numeric on-screen keypad. Another nifty feature is the category view. XM organizes their channels into groups based on the genre of music, news, or entertainment. The unit displays a list of all the available categories. The user can then select a category (boop) to see a sublist of all the channels in that category, and then touch the screen to select a channel (boop). With 120+ channels, this unit offers absolutely the best way to access all that XM offers.
