I've read posts for Vais Soundlinq & Dice Silverline options, but I'm not planning to use an ipod, so I'd rather not pay for the extra features of on-screen integration. I'm ok just using my mp3 player's controls.

I see that Grom Audio has options for an Aux only adapter for $59. Anyone used it? Any Issues? Can I still switch between the Grom & my CD Changer?

I also saw that they had a product that is one step up that would allow you to use your CD controls to page through mp3's with a directly connected usb drive (no mp3 player needed) - $125. Anyone used this?

Looks cool. It is good to see other companies coming out with product. Anyone have experience with it?

Much inexpensive then VAIS... I was looking for an IPOD adapter. I will definitely try this out.
Thanks for the post.

Thanks a lot man for the post! I been looking for it a long time! USB music the best!

WARNING!!!!!!! I purchase GROM-USB2 for my 2006 GS300 and it does not work! Grom Audio send me USB unit and 4GB USB memory card. First, when i install the unit - USB work just fine, but next day it was completely DEAD! I replace 4GB usb to my own 1GB and it was good for one day. Next morning it was all the same, I can`t make audio turn on. They send me a replacement unit and new 4GB USB card (they sad Memory Card was bad and nothing wrong with USB Unit itself. I ask for BRAND NEW unit). Install new one and guess what?! Same thing! USB audio from memory card work for a couple hours and then died. It`s turn on and off by it self. The USB unit also have AUX and IPod in, but i never try it if it`s work or not. Going to send it back and get my money. Good concept but bad experience.
