mirror,mirror

Hey Guys:

My son-in-law has an 07 SR5 but, it does not have the TEMP/COMPASS rearview mirror combination. I'm hoping to get him the above mentioned mirror for Christmas but, I don't want to risk him seeing me snooping 'round the interior. Question is: Can I expect the wiring for the mirror to already be there since it is an SR5 model? Should I stick with the Toyota mirror or are the Genex good enough? Need a temp/direction sending unit too...right?

Here's a guy that did the Genex one. You could message him some questions maybe.
