### 1/5 — APP DOES NOT WORK & also plagued with connection issues

*2025-10-07*

Not sure if the app currently works, regardless of radio connection it was never recognised in the app. Probably wouldn’t pay for something that’s has this level of support though. I do however very much respect the free trial before you have to buy it. 


[update] 
I purchased the app and had to refund right after. ANY BUTTON YOU PRESS CRASHES THE APP IMMEDIATELY. Also car play is available but does not work.

### 2/5 — Connection issues

### 1/5 — Download issue

*2024-12-06*

Won’t download to IPhone 16 yet will to Ipad 11. Support takes me to an Amazon ad……

### 5/5 — Update required

*2024-12-01*

Hi Paul, how can favorite Chanel’s be enter. Seems only 1 can be saved. Can the controls setup in a sirens way. Top left = volume up, top right channel up, middle left volume down, middle right channel down, bottom left = scan, button right = mute?

### 4/5 — Works great

*2024-06-24*

Would love to see radio simulation on CarPlay to stop the distraction of glancing at the radio.
