I had a 4000 mile week last week including 3 1000 mile days. I use the Boom nav as a backup to my RT Garmin z590. I had issues with BOTH.
The 1.22.0.1 update has a few bugs, but I didn't have the lock-up issues reported above. Due to issues with my z590, that I normally use with tone interrupt, I found out that the 'Enable Nav Prompts' setting doesn't persist in the "On" setting. Previous versions had issues with it persisting in the "Off" setting. They need to get this right.
All of this because the z590 kept losing comm connections with its mounting base. Then I had no voice instructions to get my attention during turns. I missed two exists because of this and the Boom prompts not staying on. I cleaned all the connections yesterday, so hopefully the Garmin will be more reliable going forward.
I had numerous issues with my WHIM and HD Evo 20s. I finally fixed that when I got home, where I unplugged the module and re-mounted my trusty old wired headset. Some folks have reported being able to use either, but I couldn't make the wired headset microphone work while the module was plugged in.
