Yeah, there are different connections for the newer radios. I do know for a fact that the Starmate replay and Xact STR7 use the same mounting plate that slides on the back, though, I've owned all three radios and used the same slide in plate for all of them. But none of these radios are really that much 'newer' except the Starmate Replay is much nicer in the aspect of getting to pause, rewind, etc. I also think its one of my favorite in car radios I've owned. Also, it uses the same power cords and such, so that'd be an easy upgrade route without re-doing the whole setup.
