Driver-side dash cupholder

My guess is there is no room behind the left side. A dealer’s parts department could give you the right side’s part number. Don’t forget the cup holders in the doors plus the lower one that slides out of the center console.

 

More cup holders?
I am impressed.
Yes, don't forget the door panel cup holder.

That slot to the left I understood to be for the Japanese market "road toll cards".
You could experiment and remove that panel/ slot and see what is behind, not sure what is involved in removal;
maybe start with the panel below the steering column. I am curious for one. Let us know the how tos and findings.

Good luck.

 

This is a high-quality GM part that I think would fit in the lower console area- could be attached with velcro or automotive double-sided trim tape. It would obviously block the single slide-out cupholder, but would provide two instead.

I've used this in other cars, including my Element.

Here’s a pic of the GM part sitting in the console.

Curious because I thought the 3 cup holders were great and I miss that in my current Rav4. My water, her water, her tea. She used the pull down one for her current drink, the slide out for her next/done one. I'd use the top of center armrest one. Why are more needed?
