I have a 2011 Chevy Suburban 1500 LTZ. I'm trying to figure out what size head unit (Double Din) would be a good fit. The stock radio is 7 inches across. I wasn't sure if I should get a head unit that is the same size considering the mounting kit might cause the new head unit to not fit, or if I should get a smaller head unit instead. This would be be first car audio set up and I'm tyring to figure out what the best fit would be before I spend any money. Any advice would help. Thanks.
