Nice integrated unit, the features are about a 3 or 4 on a scale of 1 to 5 based on buying each function by itself. Nice video system integration, great digital/hd radio solution, and love the bluetooth connectivety options, however Apple devices don't work well unless they are cable attached, probably an issue with Apples proprietary OS and APIs. However any one elses MP3 player with bluetooth appears to be controlled completely without cables.
As for nav system, I will probably continue to have to carry a real system with me. The maps have some nice functions to them, but because of someones greedy need someplace, you will have to pay $160 with tax and shipping annually to maintain accurate maps in any large city area. to pay 20% of the unit price annually to keep roads up to date is rediculous, so I will keep my Garmin in the glove box with it's lifetime quartely map updates, since I wasn't planning on putting out the expense to buy a new GPS every year which is what JVC wants you to do.
At the end of the day, it's a nice unit, but it does a really bad job of helping to incorporate your GPS function especially due to the gross margin JVC requires to maintain current maps.
