Just been trying to update the DAB software for the DNX4230DAB unit in my truck. It came up with a power on/off fault and would not proceed with the update any further.

In the trucks history, recently brought, it mentions a fault with the DAB radio but seller said it had been resolved. Think OH had it working for a bit of the journey home and nothing since then.

All the other functions seem to work fine, normal FM works lovely so its not a biggy as I still have radio BUT it should work.

Any tips, suggestions or advice?
Is this a known fault with these units?http://img.homepagemodules.de/frage.gif
