I have a JVC KW-V830BT radio. where can I find a universal steering wheel control that work with that receiver that can work with my apple phone 6. dvd cd gps and radio.

I purchased what was supposed to be a 50in JVC Roku TV. Received my TV today, and decided to measure it because although the box says 50in it looked smaller to me. Upon measuring the television I come to find out that the television only measures 44in. This is FRAUD! No one should make a purchase and be frauded this way! This is unexceptionable and I will be contacting the BBB about this immediately!
