Had a question about my headunit. Currently I have the JVC KW-AVX820 and was thinking about upgrading to the JVC KW-AVX830 which is the newest model. Was wondering what you guys thought. It will only cost me $50 to upgrade as I already have a buyer for my old one. The only thing holding me back is that my current one has a 7 band eq and the new one has 3 band eq. Is it worth it?
