Infiniti G35 2006 Service Manual – Audio, Navigation, and Electrical Systems

I’m Mike Callahan. Twenty-eight years turning wrenches in San Antonio, and I’ve seen guys blow airbags because they skipped the SRS precautions. This Infiniti G35 2006 Service Manual is 112 pages of factory electrical and audio diagnostics. If you’re working on the Bose system, NAVI unit, or window antenna, you need the OEM wiring diagram, not a third-party sketch. The manual covers the AV (Audio, Visual, Navigation & Telephone) section exclusively – that means everything from the steering wheel audio control switch resistance inspection to the speed-sensitive volume system. It’s not a full vehicle manual. But for electrical troubleshooting, it’s the only document you should trust.

SRS Precautions: Read This Before You Pop a Trim Panel

Page 1 of this manual starts with the Supplemental Restraint System precautions. “AIR BAG” and “SEAT BELT PRE-TENSIONER” warnings are printed in bold. If you ignore them, you risk deploying an airbag in your face. I’ve had to tell too many DIY guys that a meter probe in the wrong connector can set off the system. The manual also covers battery service precautions. That might sound basic, but a shorted battery terminal can fry a $600 NAVI control unit. The Infiniti engineers wrote these steps for a reason. Don’t skip them.

Wiring Diagrams for the Bose Audio System

Wiring diagrams for the base system and the Bose system are laid out separately. The manual includes schematics, wiring diagrams, and terminal reference values for the audio unit, the Bose speaker amp, and the steering wheel audio control switch. If you’re chasing a no-audio fault or a crackling speaker, you need the wiring diagram that matches your exact configuration – with or without telephone system. The Bose system has its own schematic on page 10 (per the OCR excerpt). The terminal reference values tell you what voltage or resistance to expect at each pin. That’s how you isolate a bad ground or a shorted output without replacing parts.

How Does the NAVI Self-Diagnosis Work?

The navigation system section includes a self-diagnosis function that checks the control unit, display, and communication lines. The manual walks you through the self-diagnosis operation procedure and describes each diagnosis result color (red, gray, yellow). It also covers confirmation/adjustment mode – steering angle adjustment and speed calibration. If the position of the current-location mark is off, there’s a step-by-step verification procedure. This isn’t generic advice; it’s the exact routine used by Infiniti dealerships. The 2006 model uses a separate NAVI control unit and DVD-ROM drive, and the manual gives you the terminal values for all of them.

3 Reasons to Choose OEM Documentation

Reason 1: Page 2 lists terminal and reference values for the NAVI control unit, display unit, and audio units. Aftermarket manuals often skip these values or print rounded numbers. Reason 2: The wiring diagrams are color-coded exactly like the factory harness. No translating pin numbers from a blurry photocopy. Reason 3: The window antenna repair section gives you the element check and repair method. That rear glass antenna for the radio and telephone is specific to the G35. Aftermarket sources won’t tell you the correct silver paste or cure time. This manual does.

Remove Audio Components the Right Way

The manual covers removal and installation for every audio component: the audio unit, A/C and audio controller, door speaker, tweeter behind the door mirror, rear side speaker, woofer, Bose speaker amp, and steering wheel audio control switch. Each sub-section has separate removal and installation steps. If you’re swapping the Bose amp, you’ll find the exact fastener locations and connector release tabs. No generic “remove the trim panel” advice. The 112 pages are dense with specifics. Use the Service Manual as your workbench reference.

Does this manual cover the engine or transmission?

No. This manual covers only the Audio, Visual, Navigation & Telephone System (AV) section.

What year Infiniti G35 models does this apply to?

This factory service manual is specifically for the 2006 Infiniti G35 Coupe. It was revised in August 2006 for the 2007 model year, according to the revision stamp on page 1. The electrical and audio systems covered are unique to the 2006-2007 G35 Coupe. Using it on earlier or later years may have differences in wiring and connector pinouts. Always verify the VIN and equipment level (Base vs BOSE, with/without telephone system, etc.).
