I went to the GROM website and found another interesting option: Select Toyota Lexus 98-05 Bluetooth Hands Free Car Adapter Kit
It appears to have the same functionality as the BT45TOY minus the USB option. It is also $125 less than the BT45.
Am I missing something? Has anyone else used this product? Thanks again fro the help!
I either missed that or it wasn't available when I was looking. Seems like a good option.
