My car won’t start and my whole dash is out, the car starts but turns right off. Any ideas?

Yes, if this happened just after installing the after market radio remove it and have an auto stereo shop wire it up for you.

Probably something about a security system/anti-theft that needs to be disabled or wired correctly.

Did you remove the negative battery cable b4 installing the radio? If not, check for a blown fuse
