Hi again and thanks for that information.
OK - when I hear this symptom and what was done, the most common cause is when the device is removed from the computer connection a bit too quickly - during the "setup" or "update" process.
What I would recommend for now is reconnecting the device to the computer and VERIFY that the updated maps ARE transferred to the device OR try to "reload" them.
Also, whenever the computer says it is OK to removed the device from the computer, I ALWAYS WAIT - at least an extra 30-60 seconds before physically removing the device and restarting the device. This is because sometimes computers can be configured to "cache" data that is supposed to go to a USB attached device, and the data is NOT really written to the device yet (its only in cache). you may want to do that too - any time you update a USB attached device.
Please let me know what you find or if you have any more questions.
If this has answered your question(s), please take a moment to rate MY service level (Excellent is my goal) so that I get credit for helping you with this question.
You should see some "smiley faces" or "stars" to do that, but please let me know if you do NOT see them (you may have to scroll UP or DOWN) or can not use them.
Thanks, ***** *****
