My STiR+ has stopped alerting me through the speaker. It still defects the radar and will announce with through the Escort Live app but that’s it. The Bluetooth unit also frequently freezes. The speaker works fine (announcing mode changes, etc.) The only warning I get is a red light flashing on the Bluetooth module. Is anyone else using the hard wired Bluetooth module on the STiR Plus? Any ideas? Is there a software update I need to install?
