I still cannot find the difference between the kenwood systems that are currently offered for my head unit. They make the KNA-DV2100, 3100, 4100 and now have a new one comming out, the KNA-G510 that operates on an internal hard drive and is upgradeable with an SD flash card. The 2100's can be had on ebay pretty cheap, usually less than $400 but the 4100's are always around 1G and I would like to know the differences between each unit so I could have an idea of why the latter is so much cheaper and if it is worth the extra cost for the newer ones. I emailed kenwood with a nice descriptive email asking the functional differences between the 3 units and what makes one better than the other and all they tell me is, "We have a new unit, the KNA-G510 comming out in a few months.......get that". That really answered my question well.......... So if anyone here has experience with any of these units, please give feedback on what you like and dislike and if possible some pics of it in operation. Thanks a lot!
