So my issue was a bit different from most others in that I was having trouble maintaining a connection to the Mazda Connect infotainment system in my 2015 Mazda3 with my Xperia X Compact. All the steering wheel controls would work, but the phone would only stay connected from very specific locations and bumping it could cause it to disconnect from the system and it would take several seconds to reconnect or I would need to do so manually. Sometimes this would happen several times in a row and I would need to keep adjusting the phone until I found the "sweet spot" where it would stay connected. This would happen almost every other time that I got into the vehicle and proved to be quite frustrating. This was also the case on the latest 34.2.A.0.311 phone firmware.
This past Monday I took my car in to upgrade the firmware from 55.00.750B-NA to 59.00.441A-NA and ever since then the phone has kept a solid connection to the Mazda Connect system. I've tried moving it around to different places in the car and the worst I've noticed is stutter on the bluetooth audio streaming, but not disconnects. I feel fairly confident that this has corrected my problem.
I was fairly skeptical about a radio update fixing the problem, but it's possible that there is truth to that reasoning. It's just a shame because car companies so rarely (if at all) update their software compared to phone companies. It seems like a huge oversight for end users.
