Hey everyone, today I installed the GROM USB adapter in to my RX300. I bought the Bluetooth dongle as well, as that’s the main thing I was looking for. The installation is very straightforward and only takes around 15-20 minutes. Everything is plug and play.
Included is the Included is the GROM Adapter (TOYA3), “TOYF” Harness Cable, 3.5mm input cable w/ USB female, (optional – Bluetooth Dongle ($50), iPod Cable with Charge & Control ($24.99), and I believe they sell a flush mount for the AUX ($10).
I only purchased the additional Bluetooth dongle.

Start by removing the (2) 10mm bolts at the bottom of the glovebox.

The glovebox should now be able to pull out. Give it a slight tug at all the edges and the clips should let the glovebox free.
I did not disconnect the cables on the glovebox. I believe I read somewhere that the cable was something for the airbag (don’t quote me on this). I didn’t mess with it, and there’s no need to.

At this point, I reached behind the CD changer and pulled the harness cable out. I was able to do this, and I have small hands but large fingers.
You may have more difficulty doing so, and may prefer to remove the CD changer to disconnect the harness. If that’s the case, remove these (4) 10 mm screws. Two on each side.

Feed the GROM cable thru the slit in the glovebox. Only do this if you plan on installing the GROM unit in the glovebox itself.
If you don’t want the GROM unit in your glovebox, you can find a place to mount it behind there somewhere.

If you bought the GROM Bluetooth dongle then continue with the DIY. If you did not, then bolt up the glovebox and you are done.
Plug the Bluetooth dongle into the “EXT1” port.

Now choose where you want to mount the microphone. I choose to mount it behind the rear view mirror, as it’s easiest to run the wire from there.

Connect the microphone into the Bluetooth dongle.
Be aware that you have to press the cable very hard to get to make a perfect connection and leave no gap between the two connections.

I plan on eventually moving the GROM unit somewhere behind the glovebox. But, first I want to use it for a few days and see how I like it before I mount it somewhere permanently.
As of now, I love it! The audio quality is amazing! It’s unbelievable how great it sounds! It’s definitely better than playing a CD. I’ll keep everyone updated as to where I move the GROM unit to, and how I like the GROM.
If you have any questions, or comments feel free to leave them below.

I have an iSimple IS77 installed in my RX300 as well, which I used prior to this GROM unit. And, the GROM is way better in terms of audio quality.
You're welcome!
