Review on Hizpo Navigator Bluetooth Chevrolet Silverado by Jay Buford

no installation instructions but if you understand plug and play. helps. I finally get it working. I asked for instructions. but get no answer. If I don't hear from you soon. it returns. Connecting an Android phone is intermittent. but I had to reboot the system for it to work. the reversing camera doesn't work either, have no idea how it works (no instructions!) Keys, seat belt and other alarms now go through this radio. and it's VERY noisy. I can't figure out how to turn it off. NO INSTRUCTIONS!
