IF YOU ARE USEING MAPCREATE 5 DO NOT DO THIS UPDATE. YOUR MAPPING SOFTWARE WILL NOT WORK ANY MORE. I did the upgrade last night only to find that my maps did not work anymore. I talked to Lowrance tech support just now and found that MapCreate5 is no longer supported with this software upgrade. He also said a problem had been found in the depth sounder in V2.9 and below and V3 fixes this problem. If you want to upgrade to MapCreate 6 buy it through Bass Pro shops online. FM wants $190.00 Joes is $149, and BPS is $75.

Improved digital depth
Enhanced surface clarity feature
Added map detail selection to Map Data window
Text enhancements

Here is the link if you are useing MapCreate6 and want the upgrade
