NAV UPGRADE / CONVERSION Parts for G35 G37 Q40 and Q60

Postby OWC » Tue Aug 24, 2021 6:34 pm

This is a quick guide on what parts are needed to upgrade a 2007-2008 G35 Sedan and 2008-2015 G37, Q40, or Q60 to a 2010-2015 NAVIGATION System.

Four NAV parts are typically required for the conversion:
(1) Touch Screen Display (2) Control Panel for Display (3) Faceplate / Climate Panel (4) NAV Unit / Radio Receiver

Cars with an '07-09 NAV System only require parts 1 and 4.
Cars with a BOSE Audio System (non-nav) require all four nav parts.
Cars with a Base Audio System require all four nav parts and need to: (5) Add an amplifier to power the car speakers.
Base Audio System cars with no factory rear camera should also: (6) Install a microphone, for voice communication.

PARTS FOR THE CONVERSION

(1) Touch Screen Display
From a 2010-2015 G37, Q40, Q60, EX35, EX37, or QX50 with Nav.
Part No: 28091-1BY3A, 28091-1BY3B, 28091-1BY1E, 28091-1BY1F, or 28091-1BY3C.

(2) Control Panel for Display (not needed for 07-09 NAV cars)
From a 2008-2015 G37, Q40, Q60, EX35, EX37, or QX50 with Nav.
Part No: 28395-1UF1A, 28395-1UF2A, 28395-JK605, 28395-JK65B, or 28395-JK66B.

(3) Faceplate / Climate Panel (optional for 07-09 NAV cars, the existing faceplate can be reused)
From a 2010-2015 G37, Q40, or Q60 with Nav. Part No: 25391-1UF3A.
or
From a 2008-2009 G37 with NAV. (These faceplates have a hard drive slot on them).
Part No: 25391-JK64B or 25391-JK65B

(4) NAV Unit / Radio Receiver
From a 2010-2015 G37, Q40, or Q60 with Nav.
Part No: 25915-1JA0B, 25915-1JA1E, 25915-1JA2B, 25915-3LZ1A, or 25915-3LZ1C
(Note – these nav units don't natively support RCA inputs; USB input only).
or
From a 2010 FX35, FX50, or EX35 with Nav.
Part No: 25915-ZX74A or 25915-JJ52C
(Note – these nav units support both RCA + USB inputs, however they may require dealer reprogramming to activate the rear camera, since those vehicles have around-view monitoring).

(5) 4+ Channel Amplifier - BASE Audio System Cars Only
The 2010+ NAV Unit/Radio does not have a built-in amp like the Base audio radio unit, so an external amp needs to be installed to power the car speakers.

(6) Microphone, for voice - Base Audio System Cars with no factory rear camera
These cars don't have microphone, and so should install one. From a 2008-2015 G37, Q40, or Q60. Part No: 28336-JK60A, 28336-1VZ0A, or 28336-1VZ0B.

---------------- END OF PARTS LIST ----------------

With the correct parts all you need is to either purchase a Harness Adapter Kit such as: https://www.ebay.com/itm/333982567715
https://www.ebay.com/itm/333958203751
Or Get a Factory Harness From a 2010-15 NAV Vehicle, and then pin-out, cut, & splice the connectors to your existing harness, using the FSM wiring diagrams as a reference. In some cases, additional wiring (like for the microphone) would also need to be fabricated.

And that's all there is to it. :) Everything can then be installed like it came from the factory. Get the parts you need, adapt the wiring and away you go! Updated Nav, Bluetooth, Display, etc.

Hope that helps.
