I just bought a 2000 blazer and I'm looking to upgrade the sound system and head unit. I want a touch screen head unit but I don't know what size will fit. If anyone has any recommendations please let me know. Thanx

 

I think it is a 1.5 DIN, not a double-din. They are hard to come by if even possible. Check Crutchfield.com for matches. Some people have done a double-din conversion but that looks pretty involved.

 

Or do a double din conversion. You just have to find a double din bezel on the internet or a pick yard
