Hey inmates, I am currently using a Garmin 2610 and looking to upgrade soon. I definitely want better reception and the later features/maps and my 2610 is starting to get some bugs. I have narrowed things down to the Nuvi 500 or 550 mainly due to price. It appears to be one of the lowest priced Garmin GPS units suitable for motorcycle use. However I see that this unit is already a few years old. Would I be better off waiting for a few months until after December....in other words how often does Garmin update their line? Any word on whether Garmin will be coming out with an updated or similar version of the 500/550? I am not totally comfortable buying a unit that is going on 3 years old at this point as we all know how fast technology changes. Any words of wisdom?
