@Whiplash My board just got back from repair and I can say that my BT connection problem has been solved!!! and it took only 2 weeks, and I live in BC.
FM sent me a note: "The technicians found that your Bluetooth was not working up to specification so they replaced the entire circuit board and conducted rigorous testing."
Happy Day!

@rm3327375 - you could easily attached such a BT amplifier to the fender - I think.

@rm3327375 it seems like a great idea but is there something like that on the market?

@Atomicmonkeys5 Great news - thanks for posting. Not too many boards have been reported as fixed so this is very encouraging... Do you have "0 miles" on it now?

Thanks @gsparx - Perfect!!! I assume you did your tests outside. My connection is quite good inside the house but outside - very, very bad.

@kd6tav When did you get your board? I had this problem from the beginning and I got mine in August... and I got the shipping labels in October. The weather turned wintery here so I'm sending mine for repair early next week... but I have the same question: Why do still sell them with this known BT connection issue.

Here is my update after installing Gemini. First couple days riding and playing inside the house connection was perfect. Yesterday and today the weather was great so I had a 2hrs rides on both days and unfortunately, connection got lost right after I left the house and it was very difficult to connect even when I kept iPhone near the pad. I tried again inside the house and connection is perfect... GO FIGURE!!!!
So the verdict is - Gemini didn't help my board and I will be sending it for repair.

Updated to the new firmware and tried around the house for 30 min... Yesterday in the same settings it was on and off all the time especially with light on. Today.... not even one disconnection :-) I will do more riding inside the house today and outside tomorrow (no rain in forecast) and will report but for now I'm very happy. I have my fedex shipping labels but hopefully I don't have to use them!!!!

@suboba good news - thanks. I will send mine in 2/3 weeks after weather turns unridable here.

I got the similar e-mail stating that I can send my board in to fix the problem... It looks FM figured it out what is wrong :-)
