5way detection

[Chris Apers]

Hi,
 
I'm want to be sure to detect 5way navigator with the correct version, but
there is
so many way to detect it, what is the good one and teh difference between :
 
FtrGet(navFtrCreator, navFtrVersion, &version);
 
FtrGet(sysFtrCreator, sysFtrNumFiveWayNavVersion, &version)
 
FtrGet(hsFtrCreator, hsFtrIDNavigationSupported, &version)
 
Do I need to the those three requests ?
I use : 
 
        if (!FtrGet(hsFtrCreator, hsFtrIDNavigationSupported, &version)) {
                if (version >= 2)
                        OPTIONS_SET(kOpt5WayNavigatorV2);

        } else if (!FtrGet(sysFtrCreator, sysFtrNumFiveWayNavVersion,
&version)) {
                if (version >= 1)       // why 1 ?
                        OPTIONS_SET(kOpt5WayNavigatorV2);

        } else if (!FtrGet(navFtrCreator, navFtrVersion, &version)) {
                if (version >= 1)
                        OPTIONS_SET(kOpt5WayNavigatorV1);
        }

Thanks for your help.
Chris
