Most Common Issues (All Models)

• No power / unit won't turn on: Check vehicle ignition/ACC wire connection; verify constant 12V (yellow) and switched (red) wires; check inline fuse (usually 10–15A); test battery voltage (>12V); reset unit (hold reset button or disconnect battery 10 min).
• No sound / muted output: Check mute button; ensure volume up and fader/balance centered; verify speaker wires connected (no shorts); check if parking brake wire engaged for video (if applicable); test speakers individually.
• Bluetooth pairing fails: Ensure phone Bluetooth on and discoverable; delete old pairings on both devices; restart phone and head unit; check compatibility list in manual; update firmware if available.
• Apple CarPlay / Android Auto not connecting: Use certified USB cable; try different USB port/cable; enable CarPlay/Android Auto in phone settings; check firmware update; ensure parking brake engaged (some models); restart both devices.
• Screen frozen / unresponsive touch: Perform soft reset (small reset pinhole on front panel); power cycle (disconnect battery 5–10 min); check for overheating (poor ventilation); update firmware via USB/SD.
• Radio reception poor / static: Check antenna connection (tighten plug); extend antenna fully; relocate antenna if possible; interference from LED lights or aftermarket accessories – try grounding improvements.

Touchscreen & Multimedia Models (XAV-AX / XAV-AXS Series 2023–2026)

• WebLink / smartphone mirroring issues: Install WebLink app; use compatible phone; check USB connection; update app and firmware.
• Rear camera not displaying: Verify camera wired to reverse trigger (purple/white wire); check polarity; test camera separately; ensure reverse gear signal reaches unit.
• HDMI / video input not working: Parking brake must be engaged; use compatible source; check cable quality.

Single DIN & Older Models (DSX, MEX, CDX Series)

• CD not reading / ejecting: Clean lens with CD cleaner disc; check disc compatibility (CD-R/RW may need specific formats); reset unit.
• USB not recognizing files: Format USB to FAT32; files must be MP3/WMA/AAC; avoid folders deeper than 8 levels; max 512 files per folder.

Safety note: Always disconnect vehicle battery before installation or wiring to prevent shorts. Professional installation recommended for complex wiring. Do not operate touchscreen while driving. Ensure proper ventilation to avoid overheating. Never bypass parking brake wire for video features while vehicle is in motion.
