Which one would you get any why? I want a reliable nav to get me from place to place, and i want it to sound good with my shaker 1000 system in my 05 mustang.

 

dnx hands down, newer headunit, ipod controls are 100x better, doesnt need a dvd for nav, the garmin based nav blows the pioneer away

 

I went with the 5120 for all the reasons pentavolvo gave. Plus I picked mine up at Amazon for 499 when they were blowing them out. I have been very happy with my choice. Only issue I have is with the BT200 and that is simply because my Storm Blackberry is not really compatible. Sometimes my BT works and sometimes it does not.

 

update teh BT firmware, not sure on the BB storm but for alot of smart phones it makes a hell of a difference. with iphone the BT is barely usable without firmware flash

 

so the 5120 will fit in a 2005 mustang w/ no mods?

 

I also will say the DNX, I've got the 8120 dnx and love it, like everyone else has said the navigation is very simple and easy to use. Although I also have had problems with the bluetooth, like it will cut out in the middle of a conversation and other times just not work at all, and I've allready done the update too, but I usually don't like talking on the phone and driving at the same time anyways
