OEM navi's not worth free for all the trouble of installing vs. the quality. I'll take a $99 garmin over OEM navi any day.

 

you can buy it here at infiniti parts

Yeah, currently on backorder there though.

The marketplace here is a good source, and eBay has them fairly consistently.

 

I've seen a lot people agree with you on that. First I want to start with the double bin, after seeing the pictures and how good it just looks I want to start there. Wrathernaut I also lookd into the HU you said you had, how much and where did you get itbecause i found it online saying it was on sale for 950 and the original price was about 1700

 

I picked mine up back in april of 2010, when it was the Z110BT for about $900 - $200 rebate ($700), then updated it to the Z120BT software.

 

Do you reccomend this HU? How hard was the installation? Does this have USB connection (preferably on the back so I can run the hard drive cable to the glove compartment) and rear view camera compability, features like that?

 

Yes, I recommend it. Usb in the rear, installation no harder than any other nav unit.
