I've decided to go with the Dice unit. Tweeter had them and it will be easier for me to go through them. Are there more than one options or are they all the same.

Thanks!

 

I'd go with the Peripheral PXAMG iPod adapter. It has:
1) Text support
2) Keep XM (w/ the Dice, you need to give up XM to get text support)
3) Steering wheel buttons work
4) Modular (you can add an HD radio unit)
5) Excellent sound
6) Aux input (i.e. another MP3 player, DVD player, or anything you want to put through your speakers)
7) Won a CES award this year. The PXAMG came out this year.

I'm almost positive you can get it at BestBuy for ~$150. I got mine on eBay for the same price.
I bought the HD Dice. Never installed it. But I heard there were quite a few problems. If HD radio is important to you, Dice is coming out with a Silverline version of their HD Dice unit within a few months.

 

i cannot imagine why you would get the dice over peripheral. this tweeter explanation is insane.
