What is the BIG deal? The aWatch is also a fitness tracker and has maps for biking and running so navagation is a 'freebie'. It doesn't add weight and you are not required to use it. Also it does't pee in your cereal. Let people who want it have it including other things you and I may consider useless or gimmicky.So let me get this straight. You contend that it is more convenient to use a 1.5" screen with tiny speaker for turn by turn in a car than a 4-5.5" screen with louder speaker that is likely already using your cart speakers? I'll say again, you aren't being realistic. You may have a case for walking directions, although I would contend few people actually use turn by turn for walking.

That's not turn by turn directions. So we have to memorize new patterns for left and right turn? What about a "bank" turn? I have a garmin as well, and haptic feedback for laps and heat rate is not the same as turn left. Maybe it works great. Until I see reviews that confirm that, I'll chalk it up to another gimmick like sending my heartbeat.
No harm and no foul by having extra features.
