I have an ’07 IS250 w/NAV with dealer installed XM radio. I am think about buying the Vaistech sl2i-up, which I *think* can be installed and integrated with my XM radio. I have been looking through the forums and the web in general to see if this in fact does integrate with the Lexus audio.

I am also looking for your experience on how reliable it works, the installation details and any other information you can share. Thank you.
