Just tried both of these at Honda and Acura parts websites and nothing. I then used "3917A-SEC-A01" without the "RM" and it led me to "3917A-SEC-A01CP" Printed Circuit Board 04 TSX, is this still the newer board, maybe something else was updated? I am looking for one without the XM for my 04.XM boards ARE different
Printed Circuit Board (without navigation system)/N 3917A-SEC-A01RM
Printed Circuit Board (with navigation system)/N 3917A-SEC-A51RM
You're too late. Its 7 years OR 100000 miles which ever comes first.I just purchased a 04 tsx with 44,000 miles and my radio and ac lights not working am I still under warranty?
