Replacement for carplay unit?

[EMG_72]

I inherited a car play (SCUMAXCON Car Stereo Radio RCD360 PRO3S RCD330 Wireless Carplay Android Auto OPS Bluetooth SD USB For Golf MK5 6 Passat Caddy Polo Tiguan (Backup Camera Deactived) https://amzn.eu/d/962uSUr) in my new secondhand Golf Plus.

The volume knob has stopped working and have been advised to upgrade it to a branded unit.

Any recommendations for replacements for a Golf?

Cheers
