In the beginning I had the stock setup. Then I moved to the Bluetooth module. Which was great, since I didn't have to go through the cabin, with all the cables. But then, after a few updates, it began to drop intermittently. Very frustrating since all it takes is a blink of an eye, and your hit. Then the Hi-Fi module appears, what a great addition! This is what I originally wanted. Now everything is back inside, and it's more diverse than the iPhone app, which to me is just a washed version of what it could be. The Hi-Fi Controller gives you control, over your ALP, with everything being mentioned along the way, instead of beeps and multi-colored LEDs, while,scanning the manual. Great addition! Worth everything, if you are serious about "uninterrupted coverage" and safety knowing that it won't shut down on you, when you need it the most.
