Disassembly and Assembly for Audio Unit: Assembly
WARNING: This page is about a different car, the 2008 Infiniti FX45 and 2008 Infiniti FX35. However, it is still accessible from the selected car via links, so may be relevant.
Assembly is the reverse order of disassembly.
NOTE:
Use appropriate screws for each, as screws for audio unit and display unit are different from that for unified meter and A/C amp.
