I bought this car used & love it to death but the owner's manual did not come w/ it. I downloaded the manual online but I still have a lot of questions. I know that there is a button on the steering wheel that allows you to connect it to your cellphone but it does not say how. Anyone have a clue? Also, there's a button above the ashtray/storage area on the right hand side that looks like a picture of maybe a horn? Does anyone know what this is for? It's supposed to light up but when I pressed it, nothing happened! I have too many questions but for now I would really appreciate these questions answered!! Thanks a bunch!
