I am considering installing the Kenwood DNX6990HD in my 2009 BMW E90. I am concerned that I may lose the vehicle's warning chimes after the install. Is this true? If so, is there a way to retain the chimes and is there a thread that will help show how to do this? I want to try and keep as many of the vehicle's original functions as possible.
Thanks in advance for any help that can be offered.
