I came from the PCI Elite, which is as reliable as they come but I wanted to move to stereo and utilize Bluetooth. The Trax setup far exceeded those expectations. Bluetooth range is better than expected and the quality is crystal clear. I can still use an AUX cable for my passengers as well. This technology is so clear that I subsequently upgraded all of my other hardware (headsets, helmet coms, etc). If you're on the fence and audio quality matters, choose Trax.
