We’ve previously looked at several other Lexus models. Mounting difficulty ranges from easy on the Lexus RX 350 to fairly difficult on the Lexus NX 300. This vehicle falls somewhat in between.
Lexus IS 300 Mount Analysis
A photo of the Lexus IS 300 interior accompanies this article.
The windshield is probably going to be the best place to mount a phone or GPS. The vents are small and centrally located so will also make a good choice. The dash is partially blocked by an extended infotainment display so cancels this location out.
Here’s what won’t work. The seat bolts aren’t easily accessed so no seat bolt mount will work. The vehicle is too small to easily deploy a good cup holder mount. The CD player is located right below the analog clock (huh?). However it’s located too low and close to the gear shift to make that a useful mount point.
A device larger than a phone can’t easily be mounted in this vehicle. A tablet is too large for this vehicle.
Mount Recommendations for the Lexis IS 300
So the best place to mount a phone or a GPS is going to be the windshield or air vent.
On the windshield, consider the Arkon Slim Grip Ultra Travel Mount for your phone. The cradle opens to over seven-inches which is large enough to hold a phone with or without a case (including a big thick Otterbox Defender). It has an expandable cradle with legs that can be moved from side to side to leave any port on your phone exposed for cables. The mount can be adjusted at the base and cradle. It rotates 360 degrees.
If you would like to use a Garmin GPS in this vehicle, remove the cradle from this mount. That uncovers a 17mm ball which is the exact size necessary to fit the socket on the back of a Garmin GPS cradle.
This mounting kit also includes an adhesive dash disk. The 80mm round disk adheres to a flat surface on the dash. The top of the disk is smooth so the suction cup will adhere to it just like a windshield. If using this mount on the dash, turn the phone cradle into landscape mode so the phone will fit without a problem.
The vent is the second location to consider.
The Square Jellyfish Jelly-Grip Car Air Vent Mount is one we have recommended before and they are excellent mounts. The Square Jellyfish Jelly-Grip mount can be used to hold most phones with or without a case or skin. It has a ball and socket so the cradle swivels into any orientation and is going to work best in landscape mode. This mount will work on flat vent slats that are 3/8 to 1 inch deep. The included cradle opens to 3 5/8 inches which is fairly large.
The Square Jellyfish Jelly-Grip mount can also be used for a Garmin GPS. All Garmin vehicle GPS devices made over the past ten years include a custom cradle that has a 17mm socket on the back. Remove the cradle from the Jelly-Grip mount and you have a 17mm ball. Just snap the Garmin cradle onto the Jelly-Grip mount minus the cradle and your GPS can be mounted to the air vent.
We did a full review of the Square Jellyfish mount awhile back and it’s worth reading for more information.
Summing it Up for the Lexus IS 300
So summing up our Lexus IS 300 mounting analysis, the windshield and vent are the best locations to mount a phone or GPS. The CD player, dash and seat bolt aren’t easily accessible and should be avoided. Anything larger than a phone will be difficult to mount in this vehicle.
