Issue with DUINB Single DIN Radio – Wireless CarPlay Won’t Auto-Reconnect

Question

Hi everyone,

I recently bought a DUINB single DIN radio (also known as an MP5 player) for my car. One of the main reasons I chose this model is because it supports wireless CarPlay, which is really important to me. However, I’ve been having a constant issue and haven’t been able to find a solution anywhere.

How the connection works

Since it uses wireless CarPlay, I first connect my iPhone to the radio via Bluetooth. After that, the device automatically creates a Wi-Fi connection, and CarPlay starts normally.

The problem

Whenever I get back into the car, CarPlay does not reconnect automatically. I’ve tried entering the car with Bluetooth turned on/off, and the same with Wi-Fi. But when I try to manually tap the radio’s Bluetooth connection, I get an error saying the device cannot pair with my iPhone and that I need to “forget” the device and pair it again.

So basically, every time I turn on the radio, I’m forced to forget the Bluetooth connection and repair everything from scratch. It’s becoming extremely annoying.

Has anyone experienced this or found a fix?

Any suggestions, firmware updates, or troubleshooting tips would be greatly appreciated!
