Yo,

Other than the option to have DAB, and no there's no sat nav, on the RCD, are there any other major differences?

Would they both control the existing auto-changer that's attached to my Stream-MP3?

Thanks

I've had both & RNS510 has DVD playback, higher res screen & 30gb + 15gb partition hard drive.

A good reference here-

I think both will control the 6cd changer.
