• Power Draw: Verify the combined power draw of both units does not exceed your charger or circuit’s capacity.
• Fuse Taps: If hardwiring, use add-a-circuit fuse taps to safely connect to the fuse box without damaging the vehicle’s electrical system.

Optimal Placement for Your Dash Cam and Navigation System

Correct device placement is crucial for safety and functionality. You must maintain an unobstructed view while ensuring both cameras and screens work effectively. Poor positioning can create dangerous blind spots and reduce device performance.

Avoiding Blind Spots and Signal Interference

Mount the dash cam high on the windshield, behind the rearview mirror. Place the sat nav lower on the dashboard or windshield, closer to your line of sight. This keeps the dash cam’s field of view clear while the nav screen remains readable.

Ensure the dash cam does not block the sat nav’s GPS antenna. Some materials in windshields can weaken satellite signals. Testing the GPS lock before finalizing placement is a wise step.

Securing Cables for a Safe and Tidy Car Interior

Loose cables are a major distraction and safety hazard. Route power cables along the headliner, down the A-pillar, and under the dashboard. Use adhesive cable clips or tuck wires into existing trim for a clean finish.

This prevents cables from dangling near steering wheels or gear shifts. A tidy setup also makes it easier to use both devices without tangled wires. It protects the cables from damage and wear over time.

Follow this checklist for ideal dual-device placement:

• Dash Cam Priority: Position it centrally, behind the mirror, to capture a wide, unbiased view of the road.
• Sat Nav Visibility: Angle the screen to minimize glare and reflections during daytime driving.
• Legal Compliance: Check local laws regarding windshield obstruction; most regions allow mounting in the passenger-side area or behind the mirror.
