Personally i found the 662 camera reliability poor. I was wondering if it was just me. Im speaking for the non 360 version.
Just after a few days of use the 662 camera blacked out on me. I was told i can leave the 307 wire which i did. It worked for like 3 days then It went crazy with static for the image on the screen then blacked out. I went back to my old 307 with zero issues.
Im now also using a gront 662 non 360 for a few weeks now. I did run the new 662 supplied wire this time. Just the other day when the front camera turned on the entire picture turned pink. So im waiting for that to go now. I will go back to my old 307 if that fails.
Again this is my personal experience and opinion but the quality has not been there for the 662.
