Upgrading 2003 Avalanche with back up camera, built in nav, hands free telephone

Recently purchased a 2003 Avalanche.
I would like to replace the existing radio unit with a unit that would have self contained Navigation, back up camera, and ability to have hands free use of a smartphone.
Does anyone know if there is a unit that will do this for me?

First welcome to the website!

You should talk to someone in customer service at www.crutchfield.com they can help you select the right unit and provide all the harnesses and adapters needed including the camera for backup use.

There are so many options, depends on how deep your pockets are and if you have a double din or 1.5 din size hole in the dash for the new head unit. I changed out my 2002 to a double din.
