Summary: This system only looks good and was okay for about a year then the screen started to flicker and it wouldn't find a connection for a long time....hope harman kardon learn from these experiences
Summary: This thing got me lost so many times, I was much better off without it. It often chose ridiculously out-of-the-way routes, and also tended to send me on wild goose chases for restaurants that didn't exist.
Summary: I bought the H/K 300 for its price and its big screen. It's easy to read w/o putting on my reading glasses while driving. Sound quality is fine for my old ears. But....and this is a big one for me: it won't hold a charge for more than a day! And that's w/o turning it on at all.
Summary: I have returned 2 now...the first one just quite working and the second one couldn't receive a signal. The first one was not an out of the box failure, but the second was. The maps are at least 2 years out of date. You will definately double, triple or even quadruple your U-Turns with this device.
Summary: I was generally pleased with this GPS system--my first--when it worked. I liked the big screen and it was pretty user-friendly. Occasionally it would lose signal in a weird spot, but it wasn't a big problem. About 2 weeks after we bought the thing it died--would not turn on at all.
Summary: The nice things about this unit are obvious: * the form factor * great screen * video support The bad points make me want to send it back: * The maps aren't very complete and they CANNOT be updated. Harmon Kardon's support is nonexistent and they certainly are far from providing map updates.
Summary: The unit does a good job of giving directions. Although the software is rather in-flexible. It always picks the shortest route, not necessarily the easiest route. The unit has locked up on me a number of times, requiring it to be reset. I suspect it has something to do with heat.
