So...is it worth it to find a stock navigation system (and preferably back up camera) for my h3t, or just buy a nice after market setup? How good are the stock ones?

Currently I have just the single Cd, no navigation or back up camera.

 

Go aftermarket. So many items you will have to buy to have OEM NAV and backup camera

 

I will be installing this next week on my mom's 08 Alpha.

So...I'm supposed to get a Pioneer 6.2" double din nav installed tomorrow. Now I'm being told the harness for the h3t is 115$. Is that what you saw?

 

Metra GMOS1 is about $80 from a stereo shop.
PAC RP5-GM11 is about $130 from a stereo shop.

Save lots of $ and install it yourself, buy everything you will need online.

 

I used the Appradio4 in my H3, and love it. its a great radio with a lot of features for an amazing price. Great choice.
