UPDATE!
We have identified this issue and now have a software update in place to resolve this issue. This software can be found on humminbird.com in theMyHumminbird section of our site. The new version number is 7.650.
The issue revolved around corrupt Tracks, Waypoints and Routes that were typically being created when the i-Pilot Link was abruptly taken out of a state of navigation. The description of the fix is as follows:
"Targeted bug fixes to v_7.590, addressing Tracks, Waypoints and Route (TWR) data corruption in the non-volatile ram memory. Software now ignores this type of invalid TWR data and will not save nor propogate this type of invalid TWR data."
IF your unit is currently in the reboot state, please read the attached FAQ on how to reset your unit. If you follow the instructions in this FAQ, it is unlikely that you will need to return your unit to us for service. This is very similar to the normal update process.
We sincerely apologize for the inconvenience this bug has caused. Please do not hesitate to contact us if you have any additional questions.
This release still incorporates the new feature and change for 7.590 listed below.
NEW FEATURE
Added support for the AS RC1 Bluetooth Dongle and Remote
