Unless I’m missing something, the Primus IQ doesn’t appear to be wireless. The Prodigy RF is Tekonsha’s wireless product, and is used by many Tab owners without issue. Others use the Curt Echo.
I have had success using the ECHO Smart Controller, Bluetooth-enabled paired to its mobile iPhone app. Once setup it automatically applies the trailer's electric brakes and provide a manual overide.
