Thanks for the replies everyone.

I have never had an issue exposing my phone, especially with the old BioLogic cases. They are pretty protected, and if I wipe out, the last thing I care about is my phone.

i looked at the Otterbox cases, but passed on them because of the inability to easily remove it from the case at the end of a ride (or when I go into a store). For me, the brilliance of the BioLogic cases was the easy on/off - in/out options. That really made it versatile and useful for me.

The he reason I don't use a bike computer is because I don't care about any of the features they have. I don't track speed, or anything like that. My phone was mounted for one basic reason, GPS. Over the last year I have ridden around Berlin, Melbourne, Victoria BC, and Calgary. The tracking app that I use has been invaluable for finding my way around and back home.

I originally tried with the phone in my bag, but it was useless and I found myself either lost, or in undesirable locations. I also pre-plotted my route around the Berlin Wall Trail, and used the phone to keep on the correct route.

As for headphones, I have two solutions. I originally just went with earbud Boss headphones, which would just pop out in an accident. I then switched to a pair of bluetooth ones which freed me up. The app I use also let's me adjust the volume, as does Apple's quick menu thing. I purchased an Anker external battery, and mounted it to my handlebars using a small hard case for an MP3 player and Velcro straps. I could pull the cord out and attach it to my phone to charge it. This could keep me on GPS for 10+ hours.

Now, I have a new phone, and no case solution.

After looking around a bit, the only real thing I can think of is to find a case that will work, and glue it to the old mount. See if a silicone case will fit in one of the old BioLogic Android cases, or 3D print one.

Other than that, I'm kinda screwed.
