Hello , my name is Kasio and I recently purchased a 2005 Acura TL. When I got the car the Navi required a code, but the radio was working just fine. the guy explained how I can get it from a website so I looked it up and neither code works , I checked the inspection book to where they write it down and still nothing. Then I disconnected battery to replace main relay for fan and now my radio is asking for a code. All the codes I am finding do not work at all. Please HELP!
