The Costal tech site list the kit as compatible only up to 2008. So I am confused. Has anybody successfully enable EV Mode on their 2009? If so how did you do it?
The same kit should work just fine on the '09, I'm not sure why their site just says to '08 as there were no changes b/w those two model years. There are plenty of DIY options available too--include my name in your google search and you'll find my original article and the knowledge base here has how to do it and install an OEM EV button for a much nicer functioning EV mod--but it's not invisible and not quite as easy as the Coastal kit.
