Does exactly what I expected. Works great with Rrtizan TPMS (available here at Revain). The owner's manual only mentions compatibility with Tire Minder systems, but this should work with any standard 433.92MHz TPMS system. I recently installed Rrtizan TPMS so I can keep a close eye on tire issues on my caravan. . I recently picked up my trailer from the store after a tire blew out causing over $9,000 worth of damage to the trailer. The steel straps tore a large hole in the floor of the trailer and severely damaged the upstairs kitchen cabinet. Luckily I have good insurance. In any case, I didn't want this incident to happen again, so I installed a TPMS system. I have found that the signal from the tire sensors on my trailer wheels cannot be reliably transmitted to the TPMS unit on the dash. The amp arrived today and I installed it. I parked my trunk about a meter in front of the hitch of my 21ft trailer and it picked up the signal from all the tires pretty well. A NOTICE. If you want to test your sensors without actually towing a trailer on the road, simply unscrew the sensors from the valve stems and twist them a little further - this makes the sensors think the wheels are spinning and they send signals.
