Been using the radar with my 520 for a year, and it's always worked very well. Recently switched to the 820 and I'm using the navigation audio alerts (paired with iPhone/GC mobile), but unfortunately the radar alerts are not transmitted through the phone app. I find the alerts from the 820 are difficult to hear, especially when I'm getting audio alerts via an earpiece.
Anyone know of a way to have the radar alerts also transmit with the other audio prompts into the earpiece (via GC app)?
