I contacted Nexian a couple nights ago (sorry for the delay posting) about my blanking and tracking problems with the HandyGPS. First off they were very nice on the phone and a representative picked up the phone immediately when I called (much better than Handspring's original customer service). After first hearing about my problems of the signal coming in and out while standing still in an open area the representative thought that I had a defective unit, but she wanted to talk to someone more technical. She called me back in about 10 minutes (!!), but unfortunately told me something to the effect of, "that is the way HandyGPS operates" and continued about how it is so small and that it will occasionally loose satellite lock due to "conditions." This is when things went down hill. Basically they don't think that my unit is operating incorrectly. I talked to her a lot more about how to get good signal, and the only real suggestions that I got (apart from "try to get more satellites to lock" - uh, how do I do that?) were to let the unit get a lock before I started to move and to hold it face up towards the sky out away from my body. Apparently your body can block the signal (seems to be a major problem if you plan on hiking with the unit and want to plot your route - to find your way back for example).
So, I went and tested the unit some more that night. To my surprise, when I stood still for only a couple minutes I was able to get a good satellite lock and then when I walked with the unit it retained lock for almost all of my trip, even under some trees. A few times I even had 5-7 satellites locked. Apparently once it gets a lock it does work better. During this positive test however, I got a low battery warning and then the unit froze up and locked up my Visor. I tested the batteries with a meter and in my Visor and they were still at least 50% full, so I guess the HandyGPS is sensitive about voltage.
The next day I loaded the unit up with NiMH's (NEXcells) and tried it again on a bike ride. This time once I got it outside it locked onto 3 satellites within a minute or so, and I was on my way. I did have the unit on for about 10 minutes inside, however, it did not find any satellites until I brought it outside. I placed it on the very top of a small backpack and it seemed to still have a lock. When I stopped next I realized that the unit was locked up again. After reviewing the trace I found that it had only been working for about a minute of my trip. After a soft reset the unit would not start again (error says it is not inserted properly or the batteries are too low). Since then I have not been able to get the unit to start at all with NiMH AAA's. I have yet to try alkalines again (just have not gone to buy any). Mike (and other HandyGPS owners), any experience using NiMH batteries in the Handy?
With more time testing the HandyGPS I see two main problems that will probably have me returning the unit even if it locks onto satellites reliably:
1) Battery usage. Apparently the unit needs fresh alkalines to operate for (a whopping) 4 hours. This is highly undesirable as I don't want to have to buy new batteries all the time, it NEEDS to operate on rechargeable cells and this means it needs to operate with slightly less voltage. Also I am unhappy with how the unit drains the NiMH's in the Visor. This drain seems uncalled for and out of the ordinary, especially for a springboard with its OWN batteries. It just makes things, such as a hard reset (which I experienced), all that much more likely.
2) It is not NMEA compliant. This, as most of you know, means that you have to use Nexian's software. After seeing what a GPS can do I would like to be able to navigate a predefined route, with turn info, etc., as other software (such as Solus) allows you to do - this would be very useful and considering other units can do this, I would want my unit to do this. I would also like to be able to save and view my traveled route on a PC, another feature offered by other software but not available to HandyGPS users. Granted these features may be added to UbiGo, but when and how sure can you be that they WILL be added?
So I am considering a separate GPS unit to connect to the Visor (unless there is some significant hardware/firmware upgrade for the Handy). There are several units available for about the same cost as the HandyGPS not to mention they actually WORK WELL. I will be the first to admit how cool it is to plug in a GPS unit and have the whole setup right in your hand, but if you can't reliably get your position and you can't use other more advanced software than the coolness wears off very quickly.
I will most likely wait and see what the Geode looks like (at least in betatest) before I buy something else, but right now I am considering the Garmin eTrex. I have seen it for $114, so even buying separate software still makes it competitive with the HandyGPS, and it is quite small (and can operate in heavy foliage). With that in mind, Wayne, can you comment on that abilities of your serial cable circuit to work with other GPS units. I read (in another thread I believe) that you were testing it with Garmin GPS units. The eTrex serial connection operates at 2.5V I believe so this should be okay for the Visor right? If it should work okay then I would be interested in buying one of your connectors with circuit assuming I get an eTrex, if you want to contact me directly about it my e-mail is [email protected]. For that matter anyone with HandyGPS questions can contact me there or on this forum.
