I've found that the latest firmware; 1.0.8 doesn't work correctly with iPhone 11 pro and BMW 1250 GS TFT that's also connected to BMW (Garmin) Nav 6. I can make a call that connects but there's no ringing sound or voice when answered. Before I found this I tried everything, i've become an expert on pairing and clearing the phone, nav, tft and 50R, I've done it literally 100"s of times, nothing fixed it. Until I realised that I'd used the wifi adapter to charge it just before it started doing this. not thinking that just charging it would cause a problem. But it had automatically updated to 1.0.8. Once I downgraded the firmware back to 1.0.6 everything is now working as it should. Thankfully SENA gives the function to downgrade through the App. Hope this helps others with the same problem. It took me 2 months to find.
I had the exact same issue with my Iphone 12. I went as far as having sena send me brand new units. while i was waiting for the new units to arrive i restarted my phone and all of a sudden it started working again. try restarting your iphone and then re connect them and see if that fixes the issue. it did for me.
It's a good idea whenever updating your sena to delete the phone pairing on the phone as the phone is paired to the previous firmware version. While sometimes it's ok, some updates may not work properly with the phone if the phone still shows the older firmware pairing. Re-pairing the phone to the updated sena should solve most phone problems.
Thanks for your input. As i said in the post. I was at it for 2 months trying, during that time I did many re-sets of Iphone, TFT, Nav VI and the Sena, the only way was to back date the Sena. It now works ok with 1.0.6.
I've heard that there are sometimes issues that occur with BMW and Garmin integration when Sena updates. A lot of folks have just paired the phone separately - secondary mobile phone pairing.
where did you found the older versions? The device manager offers only the acual 1.09 version.
It looks like Sena have taken down the old firmware versions downloads.
Once you have the .img file you can do it in Device Manager by selecting browse then selecting the older firmware file.
I would go through support and ask them to provide you with the fix. I believe that some headsets with the newer chip cannot go back without damage.
If you don't gat anywhere with support I would happily supply you with the 1.0.6 firmware, just don't want to create a bigger problem for you.
New version 1.1 doesn't fix this. Still with no sound on phone calls. I'm downgrading to 1.07 again... What a mess!
