I was able to get Toyota install sheets from sandman for Sirius and Metrotpn for XM. I have attached them to this thread.
Thanks for the info, I hope to be able to complete this and not have to pay the dealership 300 bucks to do it for me!
While I can't comment on the XM instructions, aren't the Sirius ones way out of date? The Sirius document does not show the new 2 piece unit that everyone has been buying lately for about $150.00.
