I debated putting a GPS tracker on my PV2+ and finally have. I researched so many and I finally settled on this because of its features. Its made by Pocket Finder and it is very small and works nationwide. It provides realtime locations overlayed onto Google Maps, updates every 2 mins, provides heading, GPS Coordinates, Speed, and records 60 days worth of tracking history so it will literally show me the exact path of my PV2+ for up to 60 days. You can retrieve the data via their phone app or pc and you can also visually see how many satellites its receiving, battery strength, closest address, sends sms text when battery is low, you can set zone alarms, and so much more. Its really amazing. The unit cost me $118 via amazon with a 12.00 per month fee but its worth every dime. I have tested it hard for the past two days and its accurate to just a few feet. Very Impressed. I have attached a photo to show my instillation with velcro and I can still access the battery with no problem. It comes with a drop in charger and receives a full charge in 4 hours that last 6 days set on a 2 min update which is customizable. I highly recommend the Pocket Finder!
