Hello, I seemed to have lost my user manual for the Panasonic CQ-C5301U and do not know how to properly remove it form my old vehicle to my new one. Is there a pdf or doc version of this product manual that's available for download? If not, please send me detailed step-by-step instructions on how to remove this unit from my vehicle, including what type of tools (screwdrivers) are needed. Please let me know asap!
