VEHICLE FITMENT

Acura TL

Known direct applications for this exact 39540-SEP-A420-M1 unit:

  • 2004 Acura TL
  • 2005 Acura TL
  • 2006 Acura TL

For vehicles equipped with the factory navigation system.

Compatible transmission configurations can include both automatic and manual TL models depending on original equipment.

Important

This unit is not required on TL models that were not originally equipped with factory navigation.

Always compare the number on your existing navigation unit before purchasing.


FITMENT WARNING

Acura used different navigation hardware and revisions throughout the third-generation TL.

Do not purchase based only on:

  • Vehicle year
  • Dashboard appearance
  • Screen appearance

The safest match is:

39540-SEP-A420-M1

The unit should visually and electronically match the original navigation computer installed in the vehicle.


OEM / RELATED ACURA NUMBERS

The Acura parts catalog identifies the earlier factory navigation unit family as:

  • 39540-SEP-A41
  • 39540-SEP-405

with 39540-SEP-405 listed as replacing 39540-SEP-A41 for certain 2004 Acura TL configurations.

The 39540-SEP-A420-M1 marking is commonly found on later Alpine production/navigation computers used in 2004–2006 TL vehicles.

IMPORTANT

Do not automatically assume 39540-SEP-405, A41, A410-M1, or A420-M1 are interchangeable without confirming the original unit.

Match the exact face/label number whenever possible.

  • “Disc reading error”
  • Navigation does not boot

Proper diagnosis is recommended before replacing the unit.

The navigation computer is located behind the right-side trunk access panel on factory-navigation-equipped TL models. Acura’s service procedure identifies this location when servicing the navigation DVD-ROM.

Professional installation is recommended if the buyer is unfamiliar with Acura electronics.

After replacement, the system may require:

  • Navigation security code entry
