Hello all, I recently had an 8200Nex installed on my car. When I get and turn the car on there is an annoying series of beeps (Usually 3- longer if my door is open while I start the car). Is this a standard feature and can it be disabled? Please note that I am not referring to the beeps that sound when you press buttons. I disabled that from the setting menu. Thanks for your help!
