I really like how it has tons of tracks preprogramed, including Barber where I'm going in 10 days. I'll post a review of the app after Barber with video integration. I got the Qstarz 818xt gps because the stock gps is only accurate to 100 feet at 90mph and the qstarz is 10 feet at 90 mph. 1 Hz vs. 10Hz.
