If you remove the T122 Wireless Interface from your tacktick system the the critical course and speed over ground information from the GPS can't be used to calculate true wind.

That's all that's needed to make the system a non-integrated one right?

:: To be clear, Tacktick would be "integrated", as it
:: calculates information such as true wind angle & true
:: windspeed from apparent boat speed, apparent wind angle,
:: and apparent wind speed.
::
:: Velocitek is not integrated, as it only recieves
:: information from the GPS and does its calculations
:: without further input (well, user input only). I'm not
:: familiar with Rockbox, but it sounds the same.
::
:: Instruments on board can tell you:
::
:: boatspeed

:: apparent wind angle

:: apparent wind speed

:: heading

:: depth

:: GPS information and anything computed within a single
:: device (location, SOG, computed distance, etc). Plugging
:: a GPS into any other device to get results would not be
:: allowed.
::
:: I think that's it, but I may have missed some...
::
:: As Will says, if you buy an integrated system, you are
:: on the honor system not to use anything but the
:: information listed above.
