Hi Craig, the local cannondale dealer updated the software for me and it has been working fine since. Just out of curiosity how did you manage to install the files yourself? I was under the impression that you needed the dealer app to do this, if not I will be in touch if it happens again. My range extender is also orbea.Thanks for the update.
Hello Grant, my local bike shop (where I bought the bike) couldn't find the files needed to upgrade the extender...at first. Independently, I wrote to the Mahle email line, and they sent me the .bin files needed to upgrade the extender. Next, I went back to the bike shop with those files and asked if I could watch the whole process. They were very obliging...especially since I gave them the files. We used their dealer app (so, I really didn't do this all by myself) to get the job done. And, they didn't charge me for it since I gave them the files.
I'm still trying to figure out two things. First, where to buy the cable needed (the GCU) to do this myself. Second, how to find a sponsor to activate the Dealer App I downloaded. I would love to be able to update the firmware on my bike by myself....but that's a goal that will take some time. Best regards Grant!!
