I just install a Jensen VX7020 navigation DVD radio, a Clarion CC510 rear view backup camera, and the Meta/Axxess GMOS-Lan-01 Onstar interface into my 2009 Vibe.
I used the Scosche TA2102B trim mounting kit. The Metra trim kit in my opinion is poorly designed and molded. The left bracket does not seat nicely in the OEM dash shelf.
Bought everything from Crutchfield with the exception of Scosche...and Crutchfield credited me for the my cost of the Scosche.
Caution: the GMOS-LAN-01 was not really designed for the 2009 Vibe (even though it was list as it does....) I was told this by AXXESS tech support. And he told me what to change and that I must do some "fancy rewiring" to get it to work.... however, the OEM plugs mate with these.
There are a number changes that I had to do make this setup work. Also I had to learn the hard about a few things that I should of founded out beforehand.
Finally, you must have the Vibe Service Manual to help track all the wiring in the OEM radio plugs as well as the location of the backup light wire tap in the fuse block (under the dash.)
I did this installation in three parts...I first just installed the radio with nothing else, and used it for a few weeks, Then, I rewired the harness for the Onstar interface unit. And finally I installed the backup camera just in the last few days.
Tip: you better do your research of the wiring information that is given in the Vibe Service Manual before attempting this. And this information is scattered all over the books.
I will try to post some pictures soon.
