No intention of bashing here, just an honest question.
First, when I was a LEO, I was amazed at the number of accidents in which, cell phones and texting were the causes of "driver inattention" leading to many accidents.
Riding a motorcycle is inherently more dangerous.
Therefore, why would anyone want to enable an activity that would divert ones attention away from the job at hand!
I have Nav on my bike but, I refuse to look at the screen while in motion, lest my vision be deterred just a second to long!
