Hi iconnectivity gang! i just bought my iconnectaudio4+ on ebay. i discovered two things: 1. "Interactive Display" isn't so interactive but after trying 100 times, plugging/unplugging, tweaking and stuff it started working and became responsive. then again after restart it stopped. So my question is - is there any combination of buttons or something that makes display touch work? #2 iconnectaudio makes quiet buzz noise from the inside of box when i put my ear on it, is it normal? i hope it might be some power problem and experienced electrician can fix it and display will work properly. thank you for any response, cheers !
