I second the RWGPS thought. Been very happy with it so far and have found GPS Freakout to be quite rare. In fact, when I had it on 2 of my early rides, I contacted RWGPS. They got back to me a 7 AM the next morning and had already gone into my 2 errant rides and made appropriate corrections. Brian of RWGPS then suggested a couple of possible causes of this Freakout, which I won't bore you with . Anyhoo, he was exactly right. I fixed the one thing and--Presto!!!--no more GPSFreakout.

I had a QuadLock connection fail going over a train track and trashed a spendy phone. Very disappointing. Now, I use a rather inexpensive LG, which works great, and it is mounted with the ridiculously reliable, $14 NiteIze Phone Mount, https://www.amazon.com/gp/product/B0...k_ql_qh_dp_hza. A couple of people told me I would be bothered by the straps across the screen, but I don't surf my phone while I am riding--I just look at the screen to see what's going on when necessary. If I need to make a call, I stop. If I am lost on my route, I stop. When I am riding my bicycle, I am riding my bicycle. I try to practice a bit of very unskilled but still energetic mindful riding, when I can. Consider me the Anti-Multitasker, after decades of senseless multitasking. And the data now are beginning to suggest messing with one's phone while trying to get from one place to another may be risky-completely forgetting about what we already know about cars and texting.
