It's news to me. I didn't know that you could convert DriveSmart 50 to DEZL. I have converted numerous nuvi 2460s and one nuvi 2757. All works perfectly. On splash, they show dezl 2460 and dezl 2757, but otherwise there is no difference from real dezl. I will probably try later. The dezl 580 costs five times more than the DriveSmart 50. Although it's a little outdated, it's still a truck GPS.
