HFM froze up

[5rebel9]

Well, I learned something about the HFM system operation on Saturday. Our '13 RT has always worked fine....UNTIL I paired my phone to it along with the wife's phone. Saturday we were both together and "out and about with both of us having our phones with us and found that the HFM locked up and not working even the audio voice command for radio was not working. So when we got home I went and got to the interior fuse panel and pulled the fuse for HFM, it was not blown but put a new fuse in anyway and all functions returned. I guess having multiple paired phones at the same time in the vehicle "confuses" the HFM. I guess I will have to learn to unpair my phone when we go out together BEFORE starting out when we both have our phones....She gets many more calle than I do. 

   OR does anyone have a better solution for this situation?

I have run two phones on a 2014 uconnect system for a few years. One phone is designated as the favourite. It's an older system so a little finicky, ours is an 8.4 screen but that shouldn't matter. Maybe pull both power fuses from radio so it has no power for 20 seconds. Then repair with Bluetooth to both phones. I know us older guys hate fighting with this stuff, but ....it is handy when it works right.

 

Haven't tried to update ours, but there is a firmware update on the uconnect web site. Copied to a USB jump drive and then uploaded, like map updates. I posted a link to the uconnect site a few years ago. 

 

The Bluetooth module seems to be the thing that acts up the most with these uconnect systems. There is that New Jersey guy on this site who tests and reflashes the hfm modules; gives a recore for your old one. He seems legitimate and pricing not unreasonable.

Yes, our '13 rt which did this on us is also the 8.4 screen with the alpine sound system. This was the first time that we both had our phones in the car at the same time. I could not get the settings screen to move until I "reset " the system by removing the HFM fuse and reinstalling the fuse.

  I did not get the chance to look for seeing if there was a "prefered phone" setting on the '13, I know our '17 does but we have NOT had both our phones at the same time in that car yet. I have that one set for MY phone for the '17.

When the wife gets home from work tonight, I will "check" for preferred phone setting on the '13

Unfortunately NEITHER car has NAV.

 

Thanks for the reply!
