I fabricated a bracket to mount SM3 above rear-view mirror. It attaches to stem on mirror using a collar. Just need an allen wrench. Run wire under interior trim and down A-pillar to XFI. SM can be removed easily from mirror by just disconnecting wire behind mirror and loosening collar. You can remove bracket by removing 2 screws and SM3 will be just like it was originally purchased if you do not want to install above mirror. I am selling because I purchased an XFI eDash and also have a SM3 G so do not need this one. For SM and bracket, price is $185 + 3.5% Paypal fees or send as gift. I will pay for shipping to any of the 48 states in the continental US.
