How about a replacement rearview mirror that has Homelink, auto dimming, and compass? Several people on the forum have purchased used mirrors on Ebay and replaced their stock mirrors. Do a search on Homelink and you will find a number of posts on how to install and where to tap for power in the overhead. If you don't need the Homelink feature you can get a auto dimming mirror with compass for under $70 shipped.
