This is the first TPMS I have ever used so I watched it like a hawk for the first 500 miles but then promptly forgot it was there. It was nice not having to go and check tire pressures everyday. As far as a GPS, I have been using CoPilot for 3 or 4 years now. It is a paid app so that will factor in. Being that I can run it on an iPad makes seeing it much easier too. Copilot gives you height, weight, propane restrictions as well.
