Hi I am new here and apologise if I am in the wrong forum. I have been using my infotainment system for nearly a year without a problem but recently I have the following issues: Connected via Bluetooth there is no audio, the media display shows the track/radio station information and I can see the track playing. At the same time, if I switch to the DAB radio I can see live track information but no audio. Navigation has no sound. I have factory rest the system to no avail. After leaving the system powered off sometimes the audio returns but generally if I try to connect via Bluetooth the audio fails. At all times the reverse parking proximity warning will work. I wonder if there is incompatibility of Bluetooth between the infotainment system and my phone, which begs the question, would a firmware/software update resolve the issue? I believe my system is: Amundsen MY17 unit with DAB - 5Q0035874B Hardware: H30 Software: 0353 Software train version: MST2_EU_SK_ZR_P0353T Navigation SW: H28.28.91_STD2Nav_EU Database: 5L0051236P 0730 ECE1 2017 SHIELD: SHIELD 2016-03 (build 020) If I haven't provided enough or the right information let me know how to access it and I will have another go! If I'm in the wrong forum, would you point me to the correct one please? Any/all help gratefully received, Paul
