hey guys i’ve ran into an issue on my 07’ 335i. this morning during my drive to work i had my phone connected to bluetooth on my aftermarket carplay i drive screen and it was working perfectly fine. during my drive the audio cut out for 1 min with the screen displaying small white text saying “no signal” then the screen would turn on and function properly for 5 mins, then repeating. This coupled with the orange ambient lighting turning off and the sound of the cd track spinning/ whirling when power is cut. i don’t believe is is an issue with the amp/ i drive screen because if i go to the menu for my carplay head unit the screen stay functional/ responsive while the power cut/ loss of audio. there is no sos light on the dash and i don’t know the model of head unit as the previous owner installed it. i am going to throw a battery in it to start, any suggestions or theories would be helpful
