Update: After all the problems experienced with the Connect system freezing, rebooting, tethering problems, traffic not able to work due to tethering problems (despite paying for the connected services!), and a verging on dangerous i-stop system, I had a little word with Mazda due to the perceived lack of attention from my dealer.
Mazda had previously agreed to a warranty replacement of the CMU system.
Mazda advised that the car was to be taken into the dealer again. The dealer tested the car (again) and was unable to replicate the problems, they wanted to hold on to my car for a week and put some miles on it to identify the problems. This was politely declined; I can ‘test’ and agreed to document what was happening in the car at the time. After more reboots, supplying fault reports and moaning, Mazda then agreed to another CMU replacement with the latest firmware installed.
Car was taken in and the new CMU was installed. On the test drive by the Mazda Technician after the CMU had been replaced the i-stop system failed on him, result! (I was so happy at this point!).
The fault was traced to a sensor, which was then replaced.
I now have a second CMU replacement, this one appears to be stable, I have a CMU with the latest version of the firmware and the system software has been updated to beyond the ‘current’ standard of version 33.
The unit is yet to freeze or reboot, tethering works all the time (so far), and for the first time since purchasing the vehicle it connected to my home Wi-Fi and I can update traffic info etc. before starting on my journey or before enabling tethering on my mobile.
The i-stop functions too, it’s so different from what I had been experiencing, and does not just leave you stranded at a junction either. After 7 months of ownership, it finally feels like I have the car I was hoping to purchase. Love the zoom zoom, and now hope I get to enjoy the full ownership experience. Just a shame it took 7 months, and 4 months wasted subscription to the connect services.
Need to get the other one in and get the upgrades on that too.
