I got mine from Visualgarage, I didn't have a chance to install it yet.
It looks real nice, if you want a picture of it not installed let me know.
I sent Visualgarage an email about the antenna for my 2010 Terrain, this is the emailI received from them:
Our pre-released Mark II VG shark fin antenna is compatible with your 2010 GMC Terrain. For more information, pictures and how to order, please see the email below.
This new shark fin antenna was developed specifically for vehicles that have an AM/FM rear-roof whip antenna and a Sirius/XM/OnStar/GPS chip-set antenna integrated into the larger antenna base. Our Mark II antenna will allow you to replace the whip portion of your AM/FM antenna and cover the entire large antenna base on your roof to give it a clean look. Installing this antenna will not hinder the operation of your Sirius/XM/OnStar/GPS chip-set antennas that are integrated into your antenna base. Please click the following links for some sample pictures of our new shark fin antenna:
We are happy to announce that we can continue to offer our Mark II version at the same price as our Mark I version, currently priced at $69USD (including painting to your OEM color as usual), plus shipping/handling for $12USD to USA/Canada or $28USD to International locations (including tracking number & insurance).
