i got a alpine blackbird ... it got horrible reviews from many places so i picked it up for half its retail ... i knew what to expect as my neighbor has one and let me tell you half the complaints are total BS ... like the mount rattling, umm its a suction cup on the window and it does not rattle it just shakes a bit if u go over a bump, like the rest of the car ... or the turn by turn not being perfect, agreed, its not, but the map is a big help and its not like you will get lost ... or the reroute being too slow, nope, just as fast as many oem units and it was made faster with a recent update ... my only complaint is its not a sirf III chipset so its not as sensitive as it could be.
