The mobile/base version of the PSR-310...
What's cool about this unit is that you can remove the case/stand and then the it can be mounted in a standard DIN-E sleeve, so for most cars, albeit with some modifications, it can be mounted in the dash. This is not new, it's something the Kenwood RZ-1 has done back 20 years ago. Unfortunatly the PSR-410 doesn't receive broadcast radio, something the Kenwood RZ1 could do.
