I recently had a chat with one of the sales managers (Charlie..can't think of the last name) at Koons Toyota in Tysons Corner while wrangling a deal for a 2005 Salsa Red Pkg 6 -- BTW the wait time was about a week so it seems that supply is about caught up with demand at least at Koons. I told him about the XM in my 2004 and strongly suggested that I wanted the same in my 2005. I gave him the scoop from Jon at PriusXM and he said one of the guys in the shop has a Prius and would do a test install on that one and mine would be next. He also said that if the Solara kit works for the Prius then there's no reason it shouldn't work in his Forerunner. That gives me hope for the Highlander too. I'll let you know how it goes. Don't expect a great deal on price but if you want peace of mind about warranty issues a dealer install is a good way to go.
