Another thing that works well for me the Seal Line water proof phone holder. I only use my phone for google Maps while exploring. One of the complaints I see on reviews is that phones get hot in enclosed cases. I don't seal it so it ventilated. When not in use it tucks out of the way. I installed a 12 volt waterproof outlet that I picked up at Wal Mart. I drilled 4 small holes and 2 tie wraps and it made for a clean install. I put one just like it on my 1993 4 wheeler back in 1993 and it still like new.
And then there's the wife worried one day when she couldn't get a hold of me. So I put the App Find My Phone on our iPad. Now she can watch me ride around. <smile>
