### 1/5 — Doesn’t work.

*2022-06-30*

“Please wait for connection to complete”. !!!!!!!!!!!!!

### 1/5 — Never have gotten it work.

*2022-03-20*

Awful app.

### 1/5 — No watch support

*2021-04-27*

It’s 2021, how has this app not been updated to offer Apple Watch support for even BASIC functions like volume and tuner control?

### 1/5 — Airstream

*2021-04-20*

Will not connect with my 2019 Airstream classic. So frustrating.

### 1/5 — 2 star

*2020-02-15*

I had it working for a little while. Now it’s broken completely. The app is trash and Bluetooth setup is trash.

### 1/5 — Not Marine Grade

*2019-06-11*

I agree with substandard performance. My amp was not working when boat was delivered.  I had to pay dealer to change because boat is large and I did not want to haul. A no thank you to big Harris boat dealer in the southeast!
Radio is horrible.  Can’t pick up stations. 
Bluetooth is a royal pain.  
Overall just not happy

### 1/5 — bluetooth won’t connect

*2019-05-10*

we have our polk system in our airstream globetrotter and this is the worst experience we’ve ever had with anything. bluetooth doesn’t stay connected and of course polk doesn’t provide a physical remote. we ended up using Anker bluetooth speakers to listen to music instead. polk needs to get on top of this and fix this issue.

### 1/5 — What everyone else said, plus 1

*2019-05-06*

Disconnects, never connects back, slow, etc. Just use usb connection or Bluetooth with this app. Polk speakers are great replacements but this app needs to be replaced!!

### 2/5 — Bluetooth drops off a lot

*2018-11-12*

Unfortunately, the Bluetooth drops off all the time, then fails to reconnect with my iPhone8. It requires several resets to reconnect the Bluetooth... sad in this high tech age...... seems like no standards to prevent these issues. Time to regulate!

### 1/5 — Useless app with an Airstream camper

*2018-10-07*

Installed in my Airstream Globetrotter and I’ve yet to get it to work after 3 months. Won’t pair with iPhone X. Countless attempts trying! 0 stars unfortunately is not an option
