What might cause a GPS navigation device to "freeze"?

I ride a Honda Goldwing with a built in GPS navigation system. For the three years since I bought this bike new it has functioned as it is supposed to, and within the limits of its antiquated input system (the screen is not a touch screen, you have to use the arrow controls to scroll through the screens to enter data). But the other day, in the midst of calculating a route to get me home, it froze. None of the controls would change the screen which was saying that my route had been 80% calculated. I had to shut the motorcycle down, then start over with entering the data. What might cause a GPS device to do this? Might it be a sign that the system will fail totally? I haven't even inquired with Honda about what it might cost to replace the software if that is the case.
 
Might need a software update.

There was a recent "glitch" in the GPS system time keeping that repeats every couple decade or so?

GPS receiver use 10 bit time and will roll over every 1024 weeks (~20 years).

Hi,

I had to log into Garmin's website and get a software patch to get my handheld hiking unit going during that latest "roll over" but my Garmin mobile car unit switched over just fine. Both are several years old. Sounds like something might just need to be flashed on the Honda. Or maybe ignore the built-in unit and get an up to date mobile with attendant bracket to hold it? Garmin sells motorcycle units, which look to me like any of their others, but I would imagine are built a little tougher to handle extra vibration and being out in the hot sun a lot. Take a look to see what they have: https://www.garmin.com/en-US/ Looking's still free!

You got one or more bits twiddled.

Best solution is to turn it off and disconnect power for thirty or so seconds.

Keep in mind that you are out in a hot (or cold) environment, subjecting it to heavy
vibration, and probably direct sun light. None of those keep computers happy.

A regular re-boot will handle 99.44% (like Ivory soap) of the problems.
