When the setting “HIGHWAY” is turned on, the XTE (Cross track error) is continually monitored while navigating to a waypoint. This setting has been replaced with an “ALARM” menu with settings for 3 alarms.

The highway width is no longer changed in the setup menu as indicated on P33 of the manual. The unit will switch to the track plot screen whenever the - ctrkey combination is pressed. Note: This feature will be activated by default on power up and may be activated from anywhere, not only the track screen, compared with the earlier centre feature noted on P9 of the manual. Activation of the centre on boat mode feature is indicated by a small hollow boat diamond between the speed and heading on the bottom line of the track area.

Unlocking is by panning the track plot screen (when the cursor gets to the edge of the screen), or zooming in until the boat moves outside the central area of the screen. Once the -ctr- key combination (simultaneous press of zoom-in and zoom-out) is pressed the track plot screen will follow the boat until the mode is “unlocked”. Simply put, the consumer pays for the product/service under a binding contract to be provided by the vendor - regardless of the proposed perspective that seems to suggest that by doing so, the paid consumer is 'stepping outside of the legal usage of the device (if you are attempting to open it up from its designated proprietary function)'.New feature – Centre on boat / follow boat. The protection does NOT lie with the manufacturer/vendor, but the consumer.

Pls refer to legal documentation of vendor-proprietary interface, especially in regards to usage throughout china: manufacturing in China has changed the implications of of the 'proprietary/sole' operation of such devices under specific conditions - implicated especially under the jurisdiction of consumer guarantees (act). I will leave the other parts to some one else, maybe there is a satisfactory answer for you out there, that does not require you breaking any terms.

It simply comes down to your license terms unless you can prove that you are allowed to unlock your device (which I doubt) you will not be able to get any advice on this particular subject of your question.
