Cheers monte, appreciate the help.
I notice the 2680 firmware has all the advantages of the 2660, but also isnt subject to the battery drain so ill maybe see about upgrading to it.
My only worry is that if the unit does have a dodgy past and i upgrade it, it'll end up blocked leaving me stranded with an unusable RNS!
And assuming it arrives and all is well, based on everyones opinions on them im certainly hoping to feel the same. Ive never seen how good the quality of DVD's are on teh screen though, so im hoping its as good, if not better than the Kenwood i saw yesterday...
