Hello all. I am a new owner of a 2014. The previous owner had the car entirely stock with no upgrades. Due to being a new driver I prefer ti have a bsckuo camera but its expensive to buy it and have the dealer activate it. At that price I was wondering if there are stereo upgrades, particularly one that supports Bluetooth, radio, gas, calling, a backup camera, and dashcamera. Please let me know what you've used and any suggestions. Thanks.
