Here we have a nice used rear view mirror with auto dimming, On-Star & Compass display, 025898 GNTX511.  This was removed from a 2008 Buick Enclave (if I remember correctly), but may fit other years as well (2007 - 2017 perhaps).  It is used but in good shape.  I don't know which other vehicles it may fit, so please look at the pictures to make sure it is the exact same item that you are needing.  I think this will work for other GM/Chevy vehicles but please check your vehicle to make sure it is the same style.  This has a 16 pin connector.

Shipping is included in the purchase price and I generally ship via the US Postal Service Ground Advantage (unless Priority is almost identical in price) and if it is a larger item, I may send it via UPS Ground instead of USPS as sometimes the costs can vary considerably depending on the destination.  I will ship Internationally but only if the buyers shipping address is in the eBay Global Shipping Program list, no exceptions.  Please realize that depending on where you live, you may have to pay sales tax when purchasing, this is not a payment that I receive and I have no control over eBay adding this cost, and it will show up when the buyer pays for the item.
