I'm still VERY happy with mine, and wou;dn't trade it for ANY factory nav unit! This one has much more to offer! I have mine with a hidden IPOD cable that connects my IPOD in the gove box. I also have the back up cam, and the bluetooth adapter which connects my cellphone. One of the reasons why I like this car so much is because of this D3 unit. Someday I'll add the XM sat unit as well. I alos have the steering wheel cable connection, so I can control the volume, and tuning for FM, and go thru the songs on the IPOD. This unit is so multifunctional that I don't think there's any other factory unit that comes close, especially for the $$. I've had mine for about 18 months now, and still VERY VERY happy with it! Only wish it came out sooner, and very glad I didn't pay more than double for the factory unit!!
