Thread: GPSMAP66st

User's go right away to pull the batteries on the GPSMAP 66

GPSMAP 66 freezes while zooming in on a map firmware Update 4.10 but I do not think it has anything to do with the firmware.

Once in awhile when I zoom in on the map and take it to the max. It seems to freeze and can not zoom back out.
Then the screen saver kick in and the next time I view the map all is working and I can zoom out again. Have never had to remove the batteries. Waiting seems to correct the freezing. This does not happen all the time. I think it has happen 3 times since I have been using the 66. It sounds like all the memory is used up for a minute or so and then clears the cache.

My 66 has 40 plus Geocaches on and 4GB SD card with full Benelux map. It does take some time to startup with all my 40 plus Geocaches on the SD card.

As for pulling the batteries on the 66 I would just wait and let it just reset itself before I would pull the batteries out.
In most cases this does work......
User's who seem to have this happen a lot might try a different map as a test to see if it is the maps fault.
This also holds true for use's who scrolling on map.
This has not happened to me and have tested scrolling 90 KM South on my map and everything is working with no lockup.
Then scrolled back up to my location and again no lockup. Then went East 10KM and back and West 10 KM and back. Not one lockup the whole time. But like I said I have my Benelux map on a 4GB SD card. Do not know if using an SD card is better then having everything on internal memory. While doing the test scrolling you do not see much of the map till you pause for a second and the map reappears on the screen then I go back to scrolling again. The KM does not move also till you pause for a second scrolling and it corrects itself also.
