Summary: I use this item for rental cars without a GPS. I also use this item with my HP5555 with My Topo topographic maps when 4-wheeling in remote locations such as Utah where we have been as far as 70 miles from a paved road. The positioning is accurate but we do not use the voice commands with the street atlas. It is reliable and rugged. We take it on hikes with the topographic maps.
Summary: I belong to a federal disaster team and need to carry a variety of equipment. Having my PDA allows me to have my calendar, my contact list, medical references and my pictures on one device. Now this sleeve converts my PDA to a GPS! The Compact Flash slot allows me to have 8 gb of additional memory too. This allows me to carry maps for all of the U.S. and Canada, including Hawaii and Puerto Rico, and I also have my music loaded on it too!
Summary: Problem: I used to have this product for 4 years. Time to time, it requires to activate Software. Suddenly, software is no longer able to be activated. Navman Tech support said my software (SMART ST 1.90) is outdated and their servers do not recognize it. They said that I should purchase latest software in order to continue using this product. I do not understand why my GPS suddenly stops working until I buy new software.
Summary: I have always wanted a portable GPS unit but couldn't see paying the $700 plus dollars that they used to sell for. I already had an older Compaq Ipaq 3765 that I was using for a variety of things when I discovered the NavMan. I was sceptical at first but this thing it GREAT. Works just like the much more expensive units with voice commands and turn by turn instructions. Set up was fast and easy.
Summary: I have no experience with GPS, so I can't really comment on it compared to other GPS units. What I can do is comment on its functionality compared to other computing devices I have used. Strengths: *Physical - The extra CF slot in the GPS receiver is a required feature to store maps. - The cigarette lighter adapter is also required as it does draw a lot of power from the iPaq's battery. Nice not having to purchase one!
Summary: I bought the Navman GPS3450 on Ebay to combine with second hand Ipaq 3955 pocket pc. Turns out I paid the same approx price as I could have gotten it from Amazon.Oh well, it was factory sealed and all the stuff was in the box. I installed the software and downloaded some maps in about 30 minutes. A test drive to lunch today shows it working pretty well. I was disappointed that there is no trip computer but otherwise it seems to work okay.
Summary: I've been using TomTom GPS software on my iPAQ for some time now but the sheer amount of cables involved in connecting to my Delorme GPS unit made for a messy car. So, I decided to check out the NavMan unit. After a bit of research it appeared that it would work with the TomTom software. Great news is that installation of the NavMan was simple, although I seem to have to activate the software that came with the NavMan unit even though I was going to use TomTom software.
Summary: I am going to return this item. I was even inclided to mark the product as defective when choosing the return reasons. This product is really bad at: 1) The GPS continues to lose signal. Even if I have updated the GPS firmware accordingly to the company's website. In many open places, it took more than 3-5 minutes to get a satellite fix and then it lost soon. 2) I am in New Jersey, however, the address of my doctor can't be found in the map.
Summary: In general, this is kind of a "you've got what you paid for" result. I tried a NAVMAN ICN630 (with no battery and no touch screen) before I purchased this so the comments are mainly based on my comparison of the two. The major issues I had with this unit are: 1) Poor signal reception -- the ICN 630 can be placed at almost any place in the car and still with a good enough reception, which is not the case for the 3450 sleeve.
