Prodigy RF Brake Controller Recommendation for a 2014 Mercedes GL 350

Question:

Hi, looking to get a brake controller for my 2014 Mercedes GL 350. It seems the Prodigy RF model works as long as I pair with a domestic tow vehicle first. Anything else I should know?

Sometimes the Prodigy RF Brake Controller part # TK94FR does require that you pair it with a domestic vehicle before it will function properly.

Other times you can get the controller to pair just fine if you follow the following instructions that are slightly modified from the installation instructions included:

1. Connect trailer to tow vehicle
2. Plug the Power Module 7-Way cable into the tow vehicle
3. The trailer 7-way must be disconnected from the power module
4. Start the vehicle engine, or sometimes you will only have to have the key on (try both since you are having problems)
5. Plug the remote hand held unit into an auxiliary power source within reach of you
6. Turn the power knob to the minimum position to where it is flashing 0.0
7. Fully depress and hold the manual override and the boost button, the display will run from P.5 to P.A, once it reaches P.A you can release the override and the boost button
8.Press and hold the brake pedal until the display shows 0.0 flashing
9. Set the power knob to greater than minimum, it should flash n.c. which means not connected
10. Re-connect the trailer 7-way to the power module, the display should read .c. (connected)
