Excellent advice. For me this is mostly a safety issue to improve contact with family, friends, roadside assistance, etc. I use my Garmin Zumo 660 for navigation with Bluetooth audio to my Uclear helmet speakers. SoCal sunshine really washes out the screen. VA may be different.
Rain or shine, unless I've broken out the little magnetic tank bag, with its clear device pocket, like on longggg trips, I usually just carry my phone in my breast pocket, and let the nice lady tell me what to do. I've been good and married getting on 22 years, so I'm used to letting some woman tell me what to do.
For the benefit of newcomers, a rundown on some of the ultra-cheapo touring gear from the Far East that has served me well can be found in my report on my
Trip to REOCNA/Triumph National Rally in Oley, PA--June 2018.
