If you haven't already heard, 3G cell phone service is rapidly disappearing. Some cell phone providers have already terminated support for 3G, and those that still support it will be out of the 3G business soon. Why is this important? The Cellular Communications Module (CCM) in the Zero SR/F and SR/S models is 3G. I had mine replaced recently under warranty and checked the label before it was installed. If you're having cellular connection issues with your SR/F or SR/S, 3G availability may be part of the problem.
The auto industry seems to be more aware of this issue than Zero. Subaru has issued two Service Bulletins relating to reprogramming or replacing 3G modules in their cars. When I talked to Zero about my defective CCM, the tech seemed surprised to hear about 3G's disappearance. Hopefully he will pass tghe word along and Zero will step up with new hardware or software (or better yet, outsource it to a competent 3rd party).
