You just have to google it. I found it once, & I'll look again and see if i can find the link. I want to change mine to a SSD so it won't get messed up when off road. I know it's an "automotive drive" so it's sturdier then a laptop drive but it still has plates that have to spin up. I also remember that the drives are EIDE which means in order to switch to SATA SSD I'll need an adapter. You need to clone the origional drive using linuxlive cd and you have to boot from 430n drive without windows as windows will write to it & screw it up. I'll see if i can find it again. It's a four year old post though.
I looked at it on my Challenger some time ago and decided against it since the iPod interface works better anyway. I just picked up another iPod at a pawn shop cheap to keep in the Ram. It doesn't have to be the latest and greatest as it's just for tunes. My wife uses my Gen1 iPhone as she doesn't keep a big selection in her SUV. Like having it all so I have all 12000 songs from my iTunes library on a 160GB iPod at 256AAC.
