kenwood newbie questions

I am looking for a double din navigation and was wondering what the diffrence is between all the models?
Also I want a rear backup camera for it to work do u have to special order one with that or can u get that somewhere else and hook it up? also do they make wireless rear view cameras for them?
Thanks Guys

 

It all depends on what you want in the system...I just installed the DNX5140 in my truck yesterday. It has the navigation built in and is ready to hook up anything else I might want in the future(bt, sat radio, hd, camera, amps, ect). But for now all I wanted was the nav and Ipod...so I went with the dnx5140. As far as the camera goes, yeah...you can just get any aftermarket camera...but kenwood has their own rearview camera and thats the route that im going.

What all do you want in the system? Do you like the volume knob or do you want a larger screen?

 

dnx5140-gps (bluetooth ready)
dnx6140-gps, bluetooth
dnx7140-gps, bluetooth 7" touch screen
dnx9140 top of line excelon 7" touch screen gps bluetooth
you can buy a rear camra for all these, hd radio, sirus, and other features you need adapters.
dnx means it has gps ddx means it gps ready you need an adapter

 

so the 7140 and the 9140 r the only ones with touch screen

 

they are all touch screen the 5140, 6140 have smaller screens with buttons on the side. the 7140 9140 have the bigger screen that take up the whole headunit and to insert a cd/dvd the unit sides down and shows the hide away insert.

 

the 7140 and 9140 have this cool feature where the screen moves at angles to reflect glare
