Mountaineer said:I just recently addedthe XM Roady2 to my 4Runner. It was a fairly easy process. I too have the Scion HU and I hooked up the XM with a PIE auxillary input adapter. I got the Roady2 with the home kit for $70 off of Ebay and the input adapter and a Bracketron vehicle specific mounting adapter from myradiostore.com for about $100. If you want good sound, I would definitely use an auxillary input adapter. Sorry I don't have any pics yet, I'll take some this weekend and post 'em.
Mountaineer said:The PIE adapter is the TOY03-AUX and the bracket is the Bracketron TOY-202-03. You can get both from myradiostore.com. I chose them because they were the first place that sold both items, had them in stock, and were priced about the same as everybody else.
