    Not the RNS-E, just the Navigation 5.0. Single CD, dot-matrix display in red only, no SD card slots. Before the RNS-E was released (I think?)

    I did have the HU out yesterday to instal a subwoofer,but thats been working fine sice it went in... I'll give it another try in 10 mins or so and see what happens. If no luck leave the fuse out over night. Cheers Bez

    Unfortuately my HU keys got nackered in the process because the release clips wouldn't come out. If it doesn't sort itself out I will order some more and check the wiring (which should be good as the connections were soldered and individually wrapped in electrical tape...

    sound like you could have a pressure fault on the speaker wires which is causing the thermal cut out to kick in to save blowing your outputs ,i would check you have no trapped wires behind the head unit.
