No sound radio

I ended up disconnecting the battery for a bit, and everything ended up working as normal.



What I learned is if not driving vehicle for a period of time, I keep the frunk ajar (removing the frunk light of course), and for winter I always use a battery tender.



I believe these cars electronics are very delicate when it comes to jumping, or for that matter, the frunk opening procedure I mentioned earlier (personally, I will never do that again).



Best wishes.

I have done that many times. Usually with the battery tender as source voltage. I have never had an issue.
