The 3A fuse doesn't blow for no reason - the player doesn't take anything like that much power during normal operation. Given that the home power input is almost wired in line with the car power, it is far more likely that there is a wiring problem than a faulty player.

Of course, a wiring mistake may well have blown the fuse and damaged the player as well - fuses don't guarantee protection and sometimes you can be unlucky. I daresay [email protected] will help you track this down, or get your player in for repair. Whether Rio or your installers pay for the repair will depend what fault we find!
