DNX8120 - relay trigger Q's (garage opener)
 

I know 8120 has two relay triggers that could be utilized to open your garage.
Did any one got that working? As far as I understand, the relay has to come from your original remote, but that's all I know about that mod. Can some one fill me in on details? Are there any issues with voltages? Mounting location for the relay (back of the unit or somewhere else?) any settings on the HU itself that need to be changed?
I do not have homelink, so that option would be very usefull to me
Any help would be apreciated

I'm in the same spot right now so if someone could help us out, that would be great.
