HandyGPS, and unbiased review:
I recently received the HandyGPS from Nexian (www.nexian.com) for my visor and had a chance to take it on a recent road trip. This is a review of the operation of the unit and my observations. I am in no way connected with Nexian or Navicom. The trip consisted of a drive from Miami, FL to Melbourne FL (just south of the Kennedy Space Center) through the following counties in Florida: Dade, Broward, Palm Beach, Martin, St. Lucie, Indian River and Brevard.
Visor unit used: Deluxe with 8Mb of ram. Ice color.
GPS Unit: The unit itself is rather small and about the size of small beeper. It is finished in a graphite color. The back of the unit (the exterior as installed in the Visor) is split in half, where the cover can be removed to install two triple A batteries. These come included with the unit, as were eveready energizers.
GPS Software: The unit has it�s own software which is linked to the visor os when it is installed in the visor. If your visor is off, it will turn the visor on and execute the GPS software that is onboard the unit itself. You can exit the software by pressing any other button on the visor or the menu options on the visor face itself. You can also insert the unit with the visor on, and the GPS software will execute.
Mapping Software: The unit as shipped from the factory does not have mapping software. This is available from Nexian�s web site at www.nexian.com. In order to download the maps, you need to enter the Serial Number and Registration ID which is located on a label on the last page of the manual. Once you have registered, you are immediately taken to the maps page where you can select the state, and then download all the maps for a specific county, or you can select the individual cities within a county. In order to have the most complete coverage, YOU NEED TO INSTALL THE ENTIRE COUNTY INTO THE VISOR. Although there is a county file with the cities, it apparently only covers those areas that are outside city boundaries. For my trip I loaded 7 complete counties and used a bit over 4Mb of ram.
Operation:
Installation: Installing the unit is as simple as removing the springboard cover and plugging it in. It turned the visor on and a disclaimer screen came on immediately warning me about the dangers of driving and operating the GPS unit at the same time. I guess the lawyers have never flown an airplane before. There is a check box to disable this disclaimer and an OK box to agree that Nexian is not responsible if you crash your vehicle while operating the GPS unit if the vehicle is in motion. The GPS software will then display a splash screen and go to GPS mode.
GPS Setup: You need to set up the init coordinates for the unit, as it will make it acquire your position faster. The default city is Los Angeles. You can scroll through the list to select your city (there are many listed,) and I did not count them, or you can enter your lat longs if you know what they are. Since I live in Miami, I selected Miami. You also set how you want date and time displayed (D/M/Y, Y/M/D, hh:mm:ss AM/PM, hh:mm:ss, etc.) There are several to fit how most cultures will want the date and time displayed. You also need to set the GMT offset for your area, and there is no Daylight Savings time option for this. You also need to set how you want speed displayed (Mph, Kph, Fps, Knots) along with the Max speed displayed (300 Mph.) The last setting is for the operating mode of which there are 5, (normal and 4 power saving modes.) The difference in the 4 power saving modes is the cycle of how often the GPS checks the satellite signals and how often it is idle. The table is available here: http://www.nexian.com/services/faq/faq.htm#q10 as the last item on the page. Their consumption numbers are on the money, using the new Energizer Titanium batteries. I found that with Duracells, the time was about 30% less (for Visor operation.)
The GPS takes about 5 minutes to acquire the satellite signals and it is recommended in the manual that you have a good view of the sky without a lot of tall buildings or trees around. This I can understand as the signal can be dispersed or blocked by these structures. I found that the GPS can acquire units in my house, but it worked better outside. In a building with a Metal roof, your dreaming! While you wait for the GPS to sync up, the dynamic information (lat/long, speed, course, bearing are grayed out. Once it does sync up, the numbers will turn dark. The first indication that the unit is seeing the satellites is that the correct date and time will be displayed. A minute or so later, the tracking information will go live.
There are three screens available with the GPS program in the unit, Main screen, Navigation screen and Satellite screen. These are available via a menu or using a command stroke (G, N, S.)
GPS Mode: In GPS mode, current date and time are displayed, Lat/Long, Bearing, Altitude (in meters only), a compass rose, a speedometer, course and speed in numeric display. All numerics display to one decimal place.
Navigation Mode: In nav mode, you can display your waypoints, course, speed, bearing, and distance to go. Waypoints are entered in two fashions, pressing an icon on the screen (will select current coordinates) or manually entering the lat/long values. Waypoints can be named. You can store up to 100 waypoints in the system, in groups of 10, which the manual calls routes. In Nav mode, the unit will display a bulls eye (your current position) and if you have a waypoint selected, a line extending out from the bulls eye in the direction of the waypoint. With a waypoint selected, bearing and distance to go are computed. When you move, the bulls eye will leave a trail on the screen showing your track. This information can be recorded and played back though I have not done this yet. I have only entered one waypoint (my house) to see how this worked.
Satellite Mode: The satellite mode screen displays two concentric circles with the compass points on the outside. Little boxes are displayed with a number (the Pseudo Random Number or PRN). Boxes in black with white numbers are satellites that the unit is currently using to calculate position. Selecting the box will display the Satellites PRN, Altitude an Azimuth (both in degrees.)
The GPS output is a proprietary format, as I loaded the Quo Vadis software, and it could not read the output of the HandyGPS, but it would display it. What was interesting is that the Quo Vadis would display the satellites and the satellite map, but I could not get Quo Vadis to lock a position. I may have not given it enough time and would need to test this again.
Map Software: The mapping software is provided by UbiGo, a division of Nexian. The map data itself comes from GDT, and covers the US and Puerto Rico. I do not know of any other countries to be included at this time. The map software itself is very easy to use and pretty straight forward. You can use the software without the GPS running. Features include:
Look up, Road, Airports, Train Stations, Metro/Subways, Hospitals, Golf Courses, Schools, and others.
Creation of your own Points Of Interest (POI�s). You can annotate the map and save this, then load it later on for reference again. I believe this creates a file that can be beamed, but I need another unit to test this.
Selecting an object and making it a goal.
Real time Tracking via GPS.
The maps seems pretty complete. The are segregated by County and City within the County. For a complete map of a county you must load both the cities and the county overview (this would have those areas that do not fall into specific cities.) Streets are labeled at the higher scales (i.e., lower numbers.)
Map use is intuitive and with sever
