Summary: I'll make this short and sweet. This unit is a piece of junk. I've used Garmin and Tom Tom in the past, and I had my share of complaints about the particular quirks of those units, but they both blow this thing away. I bought the Harman because I figured, even if the GPS function has deficiencies, it would be more that compensated by the media playing capabilities of the unit. I was wrong.
Summary: Like others I almost didn't buy this device because of others' bad reviews. I had a feeling that the people giving bad reviews were either luddites, technologically challenged, or were expecting way too much from this device. I was right. I bought this GPS not too long ago and I don't regret it one bit! The GPS works GREAT and is very easy to use. Satellites are locked onto almost instantly.
Very Bad Service and Easy to Have Quality Problem!

Summary: It is a very bad GPS. First, it can not locate the best traffic route and alway let you go much far away. Second, it is very easy to die, such as no signal on the street at all or keep locking and can not open at all. Third, their service is very bad. No phone was be received when you call them. When you write emails, Mr. Le will reply you soon and agree replace another one for you. Their shipping is fast.
Summary: I bought this GPS because it does what my girlfriend's doesn't, play music from the SD card while navigating. This was something I required due to not being able to hear the GPS over the radio. So, I just plug the head phone jack into my car stereo to reroute the sound. While it works I have been unable to get the play list to work even after extended e-mails with tech support. This is a major issue for me as it makes listening to things like audio books impossible.
Summary: Paid around 160 for this. Pros : Good screen size, Media and Traffic capabilities Cons : Couldnt get map icons to work No user manual at all in the pkg(couldnt find it online too) Screen too sensitive to touches (double clicks very often) Froze once (had to press the hard reset button) in the first few weeks of usage Takes a min or two to latch on to satellites.
Summary: I bought two GPS from amazon one for myself and one for my friend. After opening package i followed the process suggested by Harmon Kardon to start the GPS for the first time. First GPS froze while initial setup only. Even after several resets it never completed initial setup. Second unit was also facing problems in initial setup but it completed initial setup after several resets. I used that GPS for a testing it lead to wrong destination.
Summary: The Harman/Kardon gps 510NA is a GPS that gets the job done and more. The navigation is really intuitive and easy to use. I live in the Midwest and seems to me that I get a GPS lock really quickly even from a cold start. The text-to-speech is a great feature, I love it for when I have no idea where I am. When I do know where I am I like to change the voice to the British person, it just sounds cool.
Summary: Picked this up on a Gold Box deal for $200. My wife was especially interested in the MP3 capabilities, but unless you happen to have a stereo with RCA input jacks, the only way you can listen to the songs you put on it would be using the little speaker on the GPS. (I guess if you have a mini-jack plug in, you might be able to convert the two RCA's to mini-jack and plug it in that way.) But if you have neither of these options, it might just be better to get a new stereo.
Summary: Have been using it for a little over 2 weeks now and the unit has performed extremely well. Pros: - Locks signal instantly - GPS navigation seems accurate and route/re-route calculations are fast. - Works great as an Audio/Video portable player. - Excellent screen - Vast POI database - Create & sync your own playlists using Windows Media Player in MTP mode. Cons: - Responded slowly a couple of times while playing MP3's.
