The zumo 390LM is the first in the Garmin motorcycle series to be compatible with the new integrated Tire Pressure Monitor Sensor (sold separately). The system works with up to four tires so your trike or sidecar is covered. Add a Service History log that records the date, mileage, and type of maintenance performed on the bike, a case that resists fuel sprays and UV rays, lifetime map updates, and compatibility with BaseCamp route-planning software, and the zumo 390LM might just be the perfect motorcycle GPS. It's available now and has a suggested retail of $699.99. See it and the rest of the Garmin motorcycle GPS line on the company's website.
