Does anyone know how to stop the aggrevating Seat Belt buzzer on the 06 Charger? I would greatly appreciate any advice!!

After a while it should go off
But for a fix for life
Look in manule or fuse box
find the relay/fuse for the chime
remove it.

Think it'll be pretty tough to disable that. The fuse or rely that controls that will additionally control other things, meaning that the buzzer will not have a dedicated fude.
You might want to crawl under the dash and look for the box that makes this noise, although it may also integrate other circuits that you need.
Best thing to do is put your seatbelt on

Yeah that would be a good thing.
