I have an aging Aldi "Go Cruise" GPS. The OEM navigator software was a PoS so I "hacked" it and installed TomTom Navigator on it. However, its maps aren't updateable. Anyway, I've been looking around. Basically there are two brands, Garmin and TomTom which sell motorcycle dedicate GPS navigators. I'd like to hear from people who own any of the above and their views on the products. And with the Garmin, the early Nuvi bike navs had the ability for the user to enter in the bike's fuel tank capacity. Is this still the case with the current models? Do the TomToms allow this? Thanks.
