Howdy everybody! I drove home my new '05 roadster last night, and as you can imagine, I'm a happy camper right about now.

About the only project I have for the car is to make it mp3-compatible. It's equipped with the NAV unit, which can control a Chrysler #82209102 CD changer, as mentioned in previous posts. As to the availability of that unit, I don't know, but my dealership was quick to tell me that it is an option that can be purchased.

I have an Alpine CHA-S634 mp3-CD changer that I would like to install in the car. I want to install this changer and control it with the stock NAV head unit. I expect I need an Alpine to Crossfire interface, but I haven't been able to find one. I'm asking for help from Car Toys and my dealership, but I haven't gotten much yet. I've searched the forum and found some good info, but not specifically interfacing an aftermarket changer.

I hope some of you guys can help me out here!

Soundgate lists an Alpine to '05 Chrysler interface. The table says for Crossfire, "info forthcoming". I asked them, and they told me it's NOT compatible. What I'd like to know is if the Infinity NAV unit is unique, or if it's operation is the same as some other Chrysler or MB models. I'm hoping I can get an interface specified for MB or Chrysler that will work.

Does anyone here know:

Is the Crossfire NAV unit's CD changer control the same as any other '05 Chrysler models?

Is the connector different?

Is it fiber optic?

Is it the same that was in the previous generation SLK?

I've seen the Chrysler CD changer advertised as compatible with the '05 Viper. Does anyone know of an Alpine interface for that head unit? Is it an Infinity model?

I've seen on this forum that the NAV head unit is equivalent to a Becker BE6811. Does anyone know if there's an Alpine interface specified for that model?

Any help I can get would be greatly appreciated!
