We have encountered this situation since 2011 Worldwide. Here is our conclusion.

This post addresses the customers who have found that storing their Magellan Explorist 510 - 610 -710 has resulted in a GPS that will not restart.

We encountered this situation in 2011 around the World.

After extensive examination, we found this was caused by users who had accidentally run their units constantly until the unit quit.

In other cases they had stored the unit with a battery, tested it without using new batteries and then stored it without batteries.

We found out that if a critical part of the GPS received a negative battery charge from a dead or low current battery it would not restart.

Our discovery showed that when users leave the batteries in the unit, and they completely discharge the batteries reverse polarity.  The most guilt culprit are the rechargeable batteries. 

We replaced the capacitor and then charged it.  Capacitor was a (part#728-1057-10, MFG P/N MS621FEFL11E from DigiKey P/N 728-1057-ND.. 3.1VDC) and sits on the top of the motherboard.

The question to you is why would the capacitor have a reverse voltage.  One possibility is that accidentally you tested the units with older batteries that had low capacity remaining and then you removed the batteries before you stored the units.  

Australia found that the customers accidentally allowed the batteries in GPS to constantly run until they when dry.

Here is the problem, if the capacitor was allowed to be exposed to a reverse polarity it cannot be saved.  The job of this capacitor is to store critical start up data.

If you replace the capacitor, it still may be missing the software to start the GPS.

We do not have a solution.  We do have a special piece of software that is used to format and load the GPS.  However, we have never tried it on a dead unit.  Frankly, we do not believe that this software will work.
