I had the same problem with my TL when I had a battery changed and everything electrical got disconnected- you're not going to get it working without the code. If you are the legit owner of that system- you shouldn't have any problem getting your code from an Acura dealership. If you are not the legit owner of that system- I don't know what to say- you either wasted time or money- because it's not gonna work. (That feature was created to deter professional thieves from stealing built-in navigations from cars, just like the chip found in keys necessary to ignite.)
