Not sure if this is just an issue with 2012s or our insurance company's glass dealer, but check the mounting location for the rearview mirror on the replacement glass before you have it installed.
The factory glass has the rearview mirror mount about 2 inches higher on the windshield than the replacement glass. Not a major issue, except that the cord for the rearview mirror that powers the compass and backup camera isn't long enough for the new mount position. It works, but puts tension on the cord and can't be covered with the plastic clip.
Neither I nor the glass tech noticed that until after the new glass was installed. Our insurance company authorized another replacement using OEM glass since the glass dealer checked its suppliers and all their glass appears to have a different mounting location.
So short story, check the mount points first and if they don't match then get the OEM glass. It's about $700 for OEM glass vs $300 for the 3rd party glass so, like body work, insurance is going to want to use 3rd party suppliers if possible.
