I have a 02 Avalanche and I want to replace the stock GM HU. Is the opening considered double DIN or single?

I am lost on the GM HU part.
Has it got another name?

Hey whats up i was wondering if you know how to post an ad on the main page like you did?

HU = Head Unit (stock radio) the opening is extra big and I needed to kow if it is double or single DIN opening?

When working with extra big holes always use the old tape measure and find something to fit it rule.
Good Luck

Ok will do thanks

It is considered din and a half typical to use a radio install kit for single din flip out. However a double din can be used if you cut the dash up but it means the head unit must stay in the car when sold or traded and is pretty involved if you don't know what you are doing
