Hi everyone. A couple months ago I bought a Sync 2 to Sync 3 conversion kit off ebay and it was working great for a couple months. However one day when I got in my car to start it, the touchscreen didn’t turn on and was stuck on a black screen. No audio, no working climate controls, no feedback from the steering wheel controls or anything.
I noticed however if I disconnect the battery or the APIM for about 10-15mins and then reconnect it. The radio will start working again but it only works for about a week before the symptom happens again. Ive used Forscan to retrieve DTC’s which it doesn’t have any and tried to reset the APIM using forscan which does nothing. The seller that I bought it from ended up ghosting me so im at a complete lost for now. Any help would be appreciated.

Do you have a error message, if so what is it?
Black screen on startup. Head unit will only start working again temporarily if I disconnect the battery or head unit for 10-15mins and reconnect.
