I just finished a 1500 mile boat haul trip from Cape Cod to Lower Alabama and for the first time experienced continuous, annoying Garmin errors. I've owned several of their units, including early streetpilot "boxes," BMW Nav3 and several NUVI's. This trip was with a n??vi?« 1490LMT. I also use this one on my RT. My complaints on this trip are as follows.

1. I have no idea how Garmin figures the next "point ahead?" e.g., after crossing the tappan zee bridge heading on 287 towards CT, at some point I would expect to see the distance to the intersection of I 287 and I 95. Instead, I get a 50 mile ahead point where I 95 and I 91 intersect.

2. The unit allows me to ID myself as a pedestrian, bicycle or car. It therefore goes out of its way directing me to usage restricted parkways, e.g. Merrit or Baltimore Washington. I don't think a pick up w/ a boat trailer should require a purchase of a truck specific gps for a once in a lifetime tow???

3. While travelling on 95 and later 85, the unit continually directed me to local access or business routes, rather than staying on the main highway.

4. HOWEVER, when on 85 in Atlanta, it tried to direct me onto the HOV lane which requires a "GA Peach Pass"...

VERY ANNOYING... VERY DISAPPOINTED...
