I am recently experiencing an issue with ZLink and Apple Music app. Initially it will connect and play for some period of time ( usually only about 10 minutes ). Then, at random the connection drops, and the radio will stay at the Zlink screen but the phone will not connect again.
If I power off/power on the radio and the phone it will usually connect again but the issue will repeat. This seems specific to the Apple music app itself. Pandora, XM do not have this same behavior.
Specs: PX6, Android 11 radio, Kernel 4.19.193, MCU MTCH_HA_V3.89a_1
Iphone: 18.3.1

Hi Kurt,
Please update the Firmware to the latest version via the link below,here are some tips to help you get it done:
①Vivid 11 Version Make Sure your unit is PX6 Andorid 11
telenav_vivid_rk3399_11.0_ota(20250217)
1.Please download the file though the link via your computer/laptop.
(Do not rename and Unzip the file)
2.Format the USB drive before copying the Update.zip file to it, then insert it to the USB cable,and it will pop out the firmware updating tips on the screen.
(Tick the option"Wipe data and format flash")

Ok, I finally got the firmware updatred. However, now I am having trouble with the steering wheel controls + the radio app.
The steering wheel controls work intermittently and I have tried resetting, re-programming several times. I use them on the Radio app and inside CarPlay to skip tracks, volume, etc.
Secondly, I used to be able to cycle through radio channels with my steering wheel controls ( mapped to track forward and track reverse). Now, if I hit one of those on the Radio app screen, it turns the audio off and re-opens the Scout launch screen with navigation, novo, etc. showing. I then have to go back into the Radio app to hear the audio again.
Any ideas ?
