As a simple note, updating annually is a flat waste of money. The updates are AT LEAST 2 to 3 years behind anyway. There is a newer highway where I live that didn't get on the map the entire 6 years I owned my first Garmin. I'm on my second Garmin now with lifetime updates and I haven't checked if its there now, but I'm not holding my breath. You only get 2 annual updates max anyway no matter how many updates they publish. Its not a good update system at all and the very reason I go to the cheap NUVI models and not the super expensive moto oriented versions.
Updating once every 3 or 4 years is sufficient although for trails, I honestly can't say if that still holds true or not. Highway wise however, I'd replace it before I'd pay to update it even for the $500 models.
That said, I am a Garmin fan and find they tend to be as accurate as one could expect. Not perfect, but not bad either,...even a couple years out of date.
