"OK product for the price but be aware of the problems"2.5 starson by altalk
Pros: Best 3D turn by turn graphics I have seen on a number of GPS systems. Better then anticipated text to voice results. Reasonably fast satellite acquisition. Uses a mini-usb connector for charging - common with many cell phones
Cons: Very old maps; Very poor route selection.; No simple way to save addresses or create them in your PC (may work OK with outlook address book but I don't use that).
Summary: I have had a number of GPS devices from PC based to Cell Phone based to stand alone. The first one of these PDR150s I received took up to 30 minues to acquire a satellite and then dropped them frequently (while driving). I returned that for a replacement and the new one acquires satellites quite quickly. So it is up to current technology as far as I can tell.
Quality: Seems OK except for their initial quality control that resulted in a bad one initially. Feels solid. The downside is it is based on Windows CE so it has the standard Windows CE instability problems. For example, one of the most exasperating problems with GPS devices is waiting for them to lock in on the satellites. This unit does that reasonably quickly but, for some reason, this information frequently does not get passed to the mapping program. For example, currently the unit has locked onto 5 satellites but the mapping program is still "waiting for GPS signal". I suspect this is a WinCE problem but that isn't clear.
Maps: Very old maps and mine has US only - not even Canada. When I contacted Pharos they told me that they just buy map data from someone else (Navteq I think) so they seem to have no concern about the fact that they are way out of date. They did tell me they are updated sometimes (no given time period or indication of how you would find out or even how you would update the device).
Routing: Very poor. It will probably get you there but in a very peculiar path. OK for the typical traveler who is more interested in small size and usable directions - which is why I bought it. However during my test, I was less then a mile from my home and it was directing me to go 5-10 miles out of my way to get there. The route selected would have gotten me there - just not quickly. Worst I have ever seen in GPS devices
Graphics: Very good 3D graphics and autozoom for driving guidance. One of the better graphics for describing complex intersections that I have found.
Text to speech: Surprisingly good function for the price.
Route calculation: Very fast but not very good routing. Maybe the 2 are connected.
Charger: Standard mini-USB so it can use many common cell phone chargers (ie. Motorola and Blackberry) - cuts down on the number of chargers required for travel.
Mounting hardware: Very poor mounting hardware included - it comes with a window suction mount with extremely limited flexibility. Usable if you aren't too concerned about visibility or where the display actually ends up.
Usability: Aside from the typical user unfriendliness of most GPS devices (for example you have to go through 3 menu choices just to cancel the route), this has the added complication of not providing any good way to create favorites on a simpler to use device (PC for example) and transferring them to the device. It does sync through active sync so if you use Outlook address book, that might work OK. I don't so haven't evaulated it. Also backing up your addresses is not straight forward and the user manual (that is all that comes on the CD with the device) is of no value. If you are used to Windows CE and ActiveSync, then you can quickly figure this out. If not, it is non-obvious. You have to connect to the PC using ActiveSync and then explore to the SD card, find the user data folder, then back that up to your PC.
Strange quirks: It has one really odd quirk. I set my measurements to US (miles/tenths of a mile). So on the driving display, it displays everything in those units - including altitude. Altitude in miles is basically useless. On the screen that shows the satellite data, however, altitude is displayed in feet.
Other: Since it is Windows CE it is hackable and there are lots of instructions by very smart folks in various forums to help you do this. I've tried some that include various viewers (movie/picture/pdf) and they work. Of course there is no I/O capability so some of these functions have limited value. The unit also comes with a sticker across the SD card slot informing you that if you break the seal, the warranty is void so that also limits interest in some cases.
