| For ~$180 it might be the remote. To check the remote you can buy a real cheap sensor that will light up when the IR hits it. If you don't always get a signal it might be your remote and not the reciever in the mirror. I think Radio Shack has them to make sure your TV etc remotes are functioning. Maybe a google search may offer a homemade IR tester using a potato, orange juice and an old shoe? |
