Man I vacillated for a couple weeks over whether to use my phone for GPS or get a dedicated. I even read through the 18 pages posted here on the Chinese units!
I dont want anything huge and was very happy for years with my garmin quest but I lost it on one of my home moves.
Ultimately after finding decent software I decided to try the phone. I dont buy expensive phones so if I lost it I wouldn't be heart broken.
I first tried a plastic unit from Amazon from Carcaw. It was about $16 and it was worth about $3. Didnt even finish getting it installed and away it went.
Considering a buy in price minimum of $350ish for anything from garmin and not finding anything on the used market I liked I motored on and bought another mount. I figure if the phone didnt work out I could get a car focused GPS which is much cheaper than mC models and still use the mount. I live in AZ. It almost always rains at night and about 6 times a year.
This time I got one from Tackform on Amazon.
Been out with it three times all on the road but lots of twists and turns and over about 200 miles and the thing is pretty awesome. The clamp holds my Samsung J3 tightly and you really dont need the included rubber keeper, especially since it lands up behind the dash so isnt subject to wind, though I used it anyway.
The mount and the cradle are nice heavy duty aluminum and just mounting it up gives you a good feeling. I dont mind losing the phone but having it and the cradle bounce along my new tank would suck.
Its not cheap ... in quality or Price!! I went back and forth between it and the ram since I have used Ram mounts in the past with great success and love the articulating arm but I just couldnt get past the 4 small spring loaded arms and reviews that indicated that they often landed up right where a phone button was.
No such issue with this mount as the spring loaded part sits in the middle of the phone. I tried it with my Wifes J7 which is a fair bit larger than my phone and it worked just as well. Its tight .. Even on my small phone the spring clamps have a fair bit of tension!
I noticed after I purchased that they offer a model with an articulated arm for an extra $10 but I mounted mine up right next to the ignition key so the one I have works great.
Just thought I would share a nice solid bit of kit for your bike if you are so inclined. I put a matte shield on my phone screen and I have been very happy so far with the results.
