I have checked the files in the OS v31 and they dedinitely show 10.00 (1000 in the disc).

I managed to download a copy of v21.1 and loaded it into the nav. It went down to 4-1/12, the I tried to load v31 again. I thought everything was okay until the very end it said there was an error.

Now I can't load any OS onto it. The dvd drive has the lights flashing on and off intermittently, and the disc whirrs away like it's reading discs but nothing else.

I tried to reset it by unplugging it, but that didn't work. So I plugged in the Navcoder onto the iBus to see what it was doing. It recognises the nav but theirs no part numbers listed, and on the device logs it shows NAVE - RAD Device ready for reset (or something close).

Have I knackered it??
