Hello I bought this antenna together with Sony AX3200 to install on my 2003 g35. I want to keep my vehicle boss system. Do I need this antenna?

Reception is horrible. I saw another review on here saying to flip the connector around and it should pick up better reception, worked but only gave me one extra station I only can get 4 stations in the heart of Phoenix. Any ideas how to fix this?
