I've got a N2 and i have a dilemma... Screen doesn't light up sometimes doesn't even open i have 2 choices: 1. Send it in to Pioneer AGAIN (did so last year when they sent out the Flex cable free upgrade) or 2. Send it in to United Radio, via whom I have a 5 year warranty anyone think i should send it in to Pioneer again? or should i send it to United Radio? anyone have any experience (good or bad) with United? Thanks
