One day i'll mount my smart phone to the handlebar and have a USB charging port to keep it powered up --then I'll have live navigation on the fly.
I had planned to do that several years ago. Prior to retiring, I decided to buy a smart phone. My intention was to use it as my GPS. I decided not to.
First, my new cell phone, a Note 4, wasn't waterproof. That was an issue. So I bought a Garmin 590.
Then I started learning a few things. Something about iPhone cameras getting destroyed by the handlebar vibrations. My Note 4 cost me about $800 (I'm guessing...it's been awhile). I wasn't interested in finding out if a Note 4 could suffer the same fate as an iPhone.
After many years of using that Garmin 590...it departed my motorcycle. I thought I had it in the holder just fine. It went about 5 ft into the air on the first bounce. I'm glad it wasn't my phone. The Zumo XT I replaced it with cost me about half as much as the phone I could've lost.
And then the software...sucks. Most GPS programs are made for a car, and cars go from Point A to Point B. They don't want to take you on secondary roads. They really don't like to take you from Pt A to B, to C, to L on the twistiest roads around.
I can leave my Note 9 in my pocket or tank bag and it is safe and secure. The Garmin Zumo XT allows me to answer phone calls, listen to music...and most importantly direct me along the route I put into it. And if I need to find a gas station on the way, it'll do that without needing to stop and take off my gloves.
I decided long ago that if I was going to spend a large amount of the summer on the road, the last thing I wanted to do was to be stopped on the side of the road in 95F temps, trying to peer into a sun-washed out screen. It isn't just navigation, but the safety of having a dedicated GPS unit that is the issue here.
