The Lexus RZ 450e is Lexus’ first fully electric SUV in the U.S., and its interior reflects that shift. A massive 14–15” touchscreen, minimal physical controls, and a clean dash design make it modern—but also create some unique challenges when it comes to mounting a phone or tablet.
If you’re just dropping your phone into the wireless charging tray, you’re covered for basic use. But if you rely on your device for navigation, work, or frequent interaction while driving, you’ll need a mount that fits this interior without blocking that large display.

Mounting Challenges in the Lexus RZ 450e
- Large center display: limits dashboard mounting space
- High-mounted vents: can interfere with screen visibility
- Minimal flat surfaces: reduces adhesive mount options
- EV interior layout: fewer traditional mounting spots
This means you need to be more intentional about mount selection than in older Lexus models.
Best Mounting Locations
1. Driver-Side Vent (Best Overall)
The vent to the left of the steering wheel is one of the best mounting points. It keeps the phone within easy reach and doesn’t interfere with the center display. You can also consider a center vent option – the one nearest the driver.
2. Windshield (Best Adjustable Option)
The RZ has a large, reachable windshield, making suction mounts a strong option—especially those with longer arms to position the phone closer to you. Be sure this location is legal in your state. Some states have laws against this spot.
3. Cup Holder (Best for Tablets)
The rotary gear selector leaves the center console relatively open, making cup holder mounts surprisingly practical—especially for larger devices. Best for applications that aren’t accessed while driving.
Best Phone Mounts for Lexus RZ 450e
1. iOttie Easy One Touch 6 (Best Windshield Mount)
This is one of the best windshield mounts for the RZ because of its extendable arm, which helps bridge the distance created by the wide dashboard. The adjustable cradle opens wide enough to hold practically any size phone.
2. Vent Mount with Support Arm (Best Everyday Option)
A high-quality vent mount with a stabilizing arm works very well on the driver-side vent. This keeps your phone visible without blocking the infotainment system.
We recommend the andobil MagSafe vent mount. These are recommended for its ability to grasp onto the back of the vent slat with the metal hook. The MagSafe attachment works really well on all iPhone 12 or newer as well as any Android with a MagSafe compatible case.
These are some of the most solid vent mounts we have come across and wrote a full andobil review to explain the virtues.
Best Tablet Mount Option
Cup Holder Mount (Best for Larger Devices)
For tablets, a cup holder mount is the most practical solution in the RZ. It avoids the dashboard entirely and provides enough stability for larger devices.
APPS2Car makes a solid cup holder mount with a rigid stem. These fit phones and tablets.
This location is not the best for frequent access such as a GPS application but fine for an app that is setup prior to driving such as music.
Common Mounting Problems in the Lexus RZ 450e
- Blocking the touchscreen: avoid center dash mounts
- Weak vent mounts: choose reinforced designs
- Phone too far away: use extended arm mounts
- Tablet instability: avoid windshield mounting for larger devices
