Summary: best bluetooth gps product on market
Review: I have been using this for a week and am quite pleased with it. I downloaded the maps for CA and the surrounding states (AZ, NV and OR) and they all fit with room to spare in the 256 MB SD card of my 4355. I have used the Magellan several times when I rented from Hertz and I found the interface much much better. The feature that I like the best is that you could set your destination using your Outlook contacts; no need to enter address or street names.I am giving it 4.5 stars because of an annoying feature of the flashing BT blue light from the 4355 (which is not really the fault of the GPS device)when driving at night but otherwise a really great product.

Summary: GPS
Review: I have had this GPS Reciever for a month now, and it works very well. Sometimes it may be a little slow in getting a GPS signal, but the software is pretty good. Sure beats buying an in car system (the built ins from Honda, Infiniti, Nissan, etc) cost almost $2K! I paid $275 for this and another $290 (about) for the actual PDA. I think it's a really good deal. Plus I get wireless (iPaq rx3115) and all that other good stuff. All in all, a very user friendly system. Intial problems with set up have been solved with the help of the dedicated iPaq support line, which has been very friendly and nice. Surprising service for a technology company, in my opinion.

Summary: Simple, Flexible, and well designed
Review: I have used this system with both an iPAQ 1945 and 4155. Worked with almost no issues on both devices. The "puck" has never slid across my dash, since it has a rubber backing. Even in my sports car it stayed put around quick corners. I download maps of 3-5 states onto a SD card and the data seems quite accurate. I have only had one incorrect turn given in the past 4 months. The battery life is 6-7 hours and the fact that it uses the same charger as the iPAQ is great. I always keep the iPAQ plugged in and mounted to my dash at a good viewing angle. The Bluetooth connection is almost never dropped, so no complaints. The only "issue" I have is the application doesn't always close out properly, so I tend to do a soft reset after using the software. Works perfect every time once I got in this habit. Buy it and you will save time and avoid frustrations driving in unfamiliar locations.

Summary: Very impressive navigation solution!
Review: I just got a new h4155 iPaq and ordered this navigation system to go with it. I was very impressed with the level of detail in the maps and have had no reliablity issues. I think the key is mounting the device somewhere in your car (not sticking it in your pocket like a previous reviewer). I have never lost bluetooth signal with the iPaq mounted using a magnetic dash mount. For the GPS I just set it on the dash. This is really a great value for a complete navigation solution!

Summary: Buyer Beware!
Review: I ordered and returned this item 3 times from Amazon, each time I was sent a returned/used item!! Units had scratches, missing accessories and manuals. Apparently this item is a popular "use it and return it" item. Amazon apparently does not QC so check your box carefully.

Summary: Cool bit of kit
Review: I ordered this to replace a Navman unit I used to use with my 3870, however I lost the 3870 and replaced it with a 4155 and this. The good: - Excellent battery life
- Excellent GPS, locks in within a minute with cold start
- Bluetooth works great
- The unit comes with a power adaptor using the Ipaq connector meaning you only need carry one charger around
- The maps appear upto date
- Software is intuitive
- Routing is quick and auto-rerouting works well
- Spoken instructions are particularly good. I often don't use the display
- I like the points of interest and the way you can ask for a list and be directed to the nearest gas stations, restaurants etc.
- Never locked up The bad: - Only thing I've found better so far on the Navman was the map display Generally very impressed!

Summary: It is great when the GPS can acquire the signals
Review: I use this GPS with my IPAQ 1945. Pluses:
- Works great with the IPAQ 1945; good, clear voice guidance; good maps; good software
- Very straightforward, very friendly user interface -- light year ahead of my Magellan GPS. Minuses: It is great so why I gave it only three stars? - The GPS receiving unit is just a small hard plastic device and as slick as a hockey puck on your car's dashboard. I just don't know where to put it without it sliding off into the floor board each time I make a turn. I tucked it between the winshield and the dashboard, but that is not a good place as it can be very hot under the sun.
- The so-call bracket for your PCPocket is a joke. There is not a single piece of information on how it should be put together or at least how it should look like assembled. Anyway, after a some trials and errors I managed to put it together and found that it simply does not work on the car's air vent as intended. It simply cannot hold the IPAQ. It is quite frustrated because simple you cannot use this GPS receiver/IPAQ while driving unless you can find a suitable holder for your IPAQ. - For walking/hinking: Unlike other GPS's where the receiver and display is in one unit now you will have to hold two (2) devices in two hands. It simply awkward and not workable while walking/hiking. I even try to hang the GPS receiver around my neck in a clear plastic bag, but it did not work out because the receiver would bounce as I walk and make the display jittery and jumpy. So here I have, in my opinion, a technical marvel that I really like, but as a practical matter, I cannot 1) use it in my car until I can find or devise a way to safely mount the IPAQ display, and 2) walk/hike with it because it will require two hands to hold both devices!
-------------------------------------------
Additional review after three weeks, with one long trip from Texas to Florida:
- Yes, it did give opposite turn instructions a few times. My guess is that, in this case the highway exits were very close to each other and the software's position predictor probably estimated that I already missed an exit/turn and issued the turn around instructions. - Bought a Akron holder for my IPAQ, so that now it can be firmly attached to my windshield at a good viewing angle. - Bought an inexpensive cell phone case, with plastic window for the GPS receiver. This cell phone case, which holds the GPS receiver, can be clipped to my belt and the GPS receiver still can receive good satellite signals. - Found out that it will take a long time to generate and down load a big map such as the entire state of Texas. I suppose this is a function of the PDA -- not much I can do about it. - Wish that I can enter known GPS coordinates as destinations. Bummer. Overall I am a much happier camper now. I jacked it up to 4 stars!

Summary: Great buy
Review: I've been using HP iPAQ Bluetooth GPS Navigation System with iPAQ 4155 for a week now, and here is my 2 cents. Pros:
- Unit is small and doesn't have problems locating satellites in matter of seconds.
- HP provided excellent GPS Navigation software in this package. It's got everything that other, more expensive GPS systems have, if not more. Tons of points of interest are included. You can record a route, select route options, set speed alert, etc.
- Select maps that you need and put them on your storage card. Change maps as often as you need them. It is self intuitive and very easy to use.
- I like the way software zooms in automatically when it gets close to making a turn. Later, it zooms out.
- I like voce commands, notifying you of every turn.
- The unit displays not only your position, but your speed and altitude.
- Switches between day/night modes.
- The best of all IT WORKS WITH LAPTOP TOO!! All you need is any mapping software that supports GPS. I've used it with Microsoft MapPoint 2004 and USB Bluetooth on my laptop. And it works great, with the convenience of a relatively large screen.
- Great portability. Take it with you to any vehicle.
- Comes with car power adopter that you can use with your iPAQ PDA. And vice-versa, you can use your home adapter that you charge your PDA to charge GPS unit.
- Good battery life. Cons:
- Maybe a little slow with address lookup sometimes.
- PDA Holder is not the best holder out there, and you should look at some other solutions to replace the one that came w/Navigation system. It's hard to find a good to position and to firmly place it in the air vent. My iPaq is not fixed in the holder and tends to slip to one side while driving.
- Choosing destination from your contact list may not work every time, mostly because you have unit number in the address or address is not in the format that HP likes it.
- The unit might lose contact/sight w/satellites if you are surrounded w/tall buildings. I've experienced this in downtown Chicago, IL. I really like HP iPAQ Bluetooth GPS Navigation System and I think it's great product and it's worth the money. Have fun using it. P.S. If you need a good car mount try ARKON Powered PDA & GPS Mount Kit. It's powered and it has amplified speaker, it's durable and well built. It can hold up to 10lbs.
