The Lexus TX (including the TX 350 and TX 500h+) is a large, modern three-row SUV with a clean interior and a massive center display. While it’s comfortable and well-designed, it presents some real challenges when it comes to mounting a phone or tablet.
The combination of a wide dashboard, low-mounted vents, and limited flat surfaces means you can’t just throw any mount into this vehicle and expect it to work well.

Mounting Challenges in the Lexus TX
- Large center display: eliminates most dash mounting options
- Low-mounted vents: require offset or extended mounts
- Wide windshield: increases reach distance
- Limited seat bolt access: rules out floor-mounted systems
Compared to the Lexus RX, the TX feels wider and slightly more restrictive for mounting. It also shares some design philosophy with the Lexus RZ, particularly around minimizing physical controls.
Best Mounting Locations
1. Windshield (Best Overall)
The windshield is the most reliable mounting point in the TX. Because of the vehicle’s size, you’ll want a mount with an extended arm to bring the phone closer to you.
2. Driver-Side Vent
This is a good option, but the low placement means you need a mount that can extend outward or downward to avoid blocking airflow and visibility.
3. Cup Holder (Best for Tablets)
The large center console and compact shifter design make the cup holder a surprisingly strong option—especially for larger devices like tablets.
Best Phone Mounts for Lexus TX
1. iOttie Easy One Touch 6 (Best Windshield Mount)
This mount works particularly well in the TX because of its telescoping arm, which helps overcome the distance from the windshield to the driver.
iOttie has been making this line for quite awhile and they sell a lot of them. Solid mounts at an attractive price.
2. Offset Vent Mount (Best Vent Option)
Because the vents sit just below the display, you need a mount that offsets or extends the phone away from the vent. Look for models with support arms or drop-down positioning.
3. MagSafe Vent Mount (Best for iPhone 12 or newer users)
If you use an iPhone, a MagSafe mount provides a clean, quick-connect solution. Just make sure the mount includes a stabilizing arm so it doesn’t shift due to the vent position.
We like to recommend the andobil line for these. Solidly made with a metal hook that contracts to grasp around the slat. Strong magnetic system that your phone snaps onto and stays put.
Best Tablet Mount Option
Cup Holder Mount (Best for Larger Devices)
For tablets, the cup holder is the only practical solution in the TX. It keeps the device stable and avoids interference with the display and vents.
We like this cup holder mount because they can be used tablets and phones. Most mounts include a cradle that is dedicated to one or the other, but not fitting both form factors.
Common Mounting Problems in the Lexus TX
- Blocking the center display: avoid dash mounts entirely
- Vent interference: use offset mounts
- Phone too far away: choose extended arm mounts
- Tablet instability: avoid windshield mounting for larger devices

Bottom Line
The Lexus TX requires a more thoughtful approach to mounting than most SUVs. The windshield is your best overall option, while vent mounts can work if properly positioned. For tablets, the cup holder is the only truly practical solution.
Choose mounts that extend, offset, and stabilize—and you’ll get a setup that works cleanly with this modern interior.
