Tip & How-To about GPS
There is a way to "persuade" many GPS units to use a specified communications port and baud rate for receiving the satellite signals. You need to have a little programming knowledge to do this. This may not be the problem with your unit, but it works on some receivers.
I cannot tell you all the exact procedures for doing so for each individual GPS receiver, but you may be able to do it yourself if you are bold enough, or have a friend who is experienced in basic programming. Make sure you backup and rename any files being modified, as improper code might put your unit to sleep...maybe forever.
All GPS receivers have a "setup" or "configuration" or "sys" file in the unit's main memory software that tells it how to startup and load all the various configurations...just like a Windows PC.
In one of the files will probably be a few lines of code as follows:
Your unit may have something similar to the above code. Find out what your communications Port is, and the Baud rate the modem is running, and that should force the GPS to run on those defaults. Some units will run ok on "auto" setting for the port. If you're game, it's worth a try.
One other little tidbit of programming info:
Something that has always annoyed me is the really slow simulation speed when you're trying to run through your route. Some units will allow a faster than 1X (real time) speed drive-through. Real time is sooooo slow. Look at this code:
Now look at this:
Which one would you rather put up with? The above information may not be feasible for everyone, but it's worth attempting if you want to try. Just be aware that it may VOID your warranty, if you're within that period.
These are just some suggestions to try. Maybe you can use them. If you do try, let me know how it works out. Thanks.
