Practical answer

Wireless charging adds heat; wired power can add cable and RF-noise problems. Test the exact case, mount, cable, adapter, screen brightness and app for longer than the intended session.

Choose a phone mount

Choose the attachment point and the phone holder together. A strong base cannot compensate for a phone that can slide out, and a secure holder cannot compensate for a loose base. The drawings below show general arrangements, not vehicle-specific mounting locations or installation dimensions.

1. Windscreen suction mount

Use a clean, smooth surface approved by the mount maker. Engage the suction lock fully and keep the arm short. Position the phone outside the driver's view of the circuit, mirrors and instruments; check the camera view separately if recording video. Test the grip with the actual phone and case fitted.

Keep the phone close to the base instead of extending several joints into the cabin.

RAM specifies glass and suitable non-porous surfaces for its suction base. Check the requirements for your exact mount: RAM short-arm suction mount reference.

2. Dashboard base

Use a manufacturer-approved dash pad or vehicle-specific bracket on a suitable surface. Do not assume that a suction cup will seal on textured or soft trim. Follow the maker's cleaning and adhesive curing instructions before loading the mount, and keep it clear of airbag covers and deployment paths.

Choose a solid attachment surface and a low arrangement; do not mount on an airbag cover.

Dashboard suitability and attachment heads vary between products. See Quad Lock's windscreen/dash mount guidance for one manufacturer's requirements.

3. Rigid clamp or vehicle-specific bracket

Where the car and organiser allow it, a correctly sized clamp on an approved rigid tube, or a suitable vehicle-specific bracket, avoids relying on flexible trim. Follow the mount's load, tube-size and tightening instructions. Do not use steering components, belt hardware or an improvised attachment that can interfere with the driver.

General arrangement only. A suitable clamp size and an approved attachment point are essential.

Retention, tether and cable routing

Fit the holder around the actual phone and case without pressing side buttons or covering the lens. Use the holder's locking mechanism and any retention accessory specified for that product. RAM, for example, supplies a device tether for its X-Grip holder; that retains the phone in the cradle and is not a substitute for securing the mount to the car.

A charging cable forms a small slack loop and is clipped to a nearby fixed surface. Holder retentionSeparate anchor*Small slack loopCable clip
*If a secondary tether is required, use the attachment points and tether specified by the equipment maker and organiser. Keep tether and cable clear of controls, belts and driver movement.

Support the charging cable so it does not pull on the phone socket. Leave only enough slack for the mount's intended adjustment and route the rest away from the steering wheel, gear lever and pedals. A cable should never act as a safety tether.

Check the installation before recording

Practical setup checks, to use alongside the product instructions and venue requirements:

  • With the car stationary, sit in the driving position and check the full range of steering, gear selection and belt movement.
  • Check the base, joints and holder for movement with the phone installed. A successful hand check does not certify a mount for circuit use.
  • Record a short sample to inspect framing and vibration. Reduce unnecessary arm length or joints if the image shakes.
  • Keep the phone out of direct sun where practical, leave ventilation around it and test the chosen charging arrangement for the intended session length.
  • Recheck the base, latch, fasteners and cable route before each session. Set recording before driving.

What to verify before track use

Position
Delivered and recorded update rate, fix quality and timestamp basis
Motion
Which sensors are exposed, axes, rate and raw versus fused values
Files
CSV, VBO, GPX, FIT, video metadata or proprietary session
Reliability
Background recording, heat, power, storage and interruptions
Do not infer a fixed GPS rate.

No fixed motorsport logging rate is claimed unless the device and app documentation explicitly provide it.

Phone + external GNSS

Improve position recording.

Phone + OBD-II

Add vehicle channels.
