Hello everyone and happy new year.

I am having an issue where the Bluetooth, amp, phone and CD changer all go dead. I have an 08 Vanden plas. It seems that all those items are in the trunk so I figure it's the connection or it's the first of those items in the daisy chain. Here is the thing it randomly happens, although colder weather seems to make it happen more. However, I live in Miami, FL so colder weather is relative. Seems to happen more when temp drops to 70's. However it seems water isn't N issue because it has happened when car is inside and dry and outside and wet due to dew point. Any info or advice would be appreciated.

Thanks.

 

Could be as simple as a loose connection, or the lack of a good ground, i'd start by looking there.
