Interesting discovery...

Anyhow, should OEM not be available, don't fret much going aftermkt as I had to do exactly that in my '04 GX using the Vaistech SLX which worked seamlessly. Plus on amazon/ebay/myradiostore.com there are antenna adapters available so you can just use the sharkfin. Incidentally, should you decide to aftermkt, if the SLX (a previous version of the afertmkt kit Sewell now offers per you p/n) is compatible w/ your '09, I know of one f/s cheap including the tuner

Good luck

 

Thank you very much for your help!

I called Sewell Lexus again, and gave them the link. They called back, and said to order it - they are told if it lets me order it, they have a vendor with one.

I ordered it, and have my fingers crossed. I will believe it when I see it, but my money is on the line, and will report back whatever happens!

Thank you all for the great help!!!!
