I have a 04 TL non-nav. I enjoy using the HFL whenever it works properly. I've always had problems with it recognizing various numbers. Believe me, I've tried every way possible to get around this but no such luck. I even stopped using it for a long time. Recently, I took the car in for servicing at Goodson Acura. The service technician said my problem could be eliminated by replacing the speaker for the HFL. Well, my problem still remains, although not as bad as before. Someone recently told me there is a software update that should help to reduce or eliminate this problem. When I asked the technician if a software update is available, I was told there wasn't. Is there or is there not a software update for this problem?
