Zandroid,
I haven't purchased the droid yet, but I wanted to make sure that it would work first. Hopefully, the Corolla and the Highlander have the same bluetooth version. Was your car manufactured before the droid came out? I tried to find out from Verizon and Toyota if the two were compatible and they told me to contact the other one, so I didn't know what to do. It sounds like it should work. Maybe I'll just buy it and try it.
Thanks for your help.
