INTRODUCTION

Hi guys... Well after a couple weeks of looking for a TSX I ran across a 2004 6spd TL for an excellent price and bought it! I must say, it's nice to have a car that I literally don't want to change a thing on. I'm sure in the future I will want to do some mods but all my previous cars I would long for more speed, bluetooth capabilities, better handling, smoother shifting, better wheels ect. but not on the TL. I love it stock. That being said I do have a problem that I knew the car had going into the deal.

THE PROBLEM

The nav unit is intermittent. When the car is on auxillery power the gps/maps/setup screens work well. The climate control screens do not show up and the voice recognition/speaking of the directions results in a hiss/crackling sound NOT a voice. No commands work although the HFL works flawlessly. When I turn the car on the navigation will do one of two things: it will either say "Downloading software... Please wait" after which the screen goes black permanently or it will show the Acura startup screen permanently.

WHAT I HAVE TRIED

I took out the disk and checked for scratches and reinstalled. I checked out the diagnostic screen and I have F-CAN and B-CAN errors as well as the "Navi System Link" screen shows the A/C, Fl-ECU and Meter boxes in red. All other screens say okay. I have read the TSB for Nov 2006 about the F-CAN and B-CAN but still need some help deciphering what they mean. I called Alpine and they said I could send the unit in for repairs but they do not provide technical support. I also called Acura's nav help line and should hear back from them tomorrow.

SUGGESTIONS?

Does anyone have any input? I have searched quite a bit but came up lacking. I know the whole "Take it to the dealer..." but my car is out of warrantee and I only have a Honda dealership nearby. Does anyone know what the F-CAN and B-CAN screens mean? Thanks in advance...
