I am looking for buy a HU for my cr-v soon and have been lurking around here for info. my budget is below 130-140 and have narrowed my search down to Pioneer deh-2200ub, Kenwood KDC-MP345U (MP342U replacement), JVC KD-HDR50 and the Sony CDX-GT640UI. I plan on using the stock speakers and my only requirement is USB to use with a thumb stick. It seems that pioneer and kenwood are fairly well respected but i am not sure about sony. any insight and suggestions would be awesome.
