So I've narrowed down my search for a H/U....there are alot of options and pretty much alot of these units are very similiar. I like the clean look of the 7" screens and have decided on JVC. So the 710 is pretty much their basic model w/ bluetooth, ipod and all that, the 810 is pretty neat, just one step up from the 710, but has a DETACHEABLE screen, which is nice for anti theft. Haven't really found out much info on the 790 as to why it's different from the 710 besides being a newer model.

Does anyone have any experience/opinions on these models? The prices for the 710 and 790 are almost the same on Ebay and the 810 is about $100 more for the detacheable screen....I'm in no hurry so just trying to do my homework!
