COBALT- my dash cam has it's own ciggie plug, but it causes problems, + it is on a non switched supply ,and other problems. I ws thinking of getting rid of plug + convertor and connecting dashcam directly hardwired from a supply that's on with ignition but via a 12-5v convertor . I've no USB in car ( it's one of the lower spec VAG MODELS, and 14 year old).
I didn't want to bring it into the post, but I'm also looking at converting my system to remote central lock ( an old ,"when I get round to it" project) , and as part of th PSU board, it would be a good idea to provide a 5v (USB) supply ,that is on with ignition. Supply to the remote locking would be disabled till ignition off.
But I have little ideas of USB supplies, or what smoothing is needed, hence my post.
