Thanks for the info TSCAD.
I'm another '07 Eos owner who's prolly going to replace his factory setup with a Pioneer (F series I think).
I'm a bit of a newb and was hoping you could fill me in on what wiring harness adapter I should buy.
Also were you able to keep Steering Wheel control?
I'll probably be ditching the Sirius unit as you did but adding the HD Radio option. Do you think it would be possible to do the under seat swap out like you did for your XM?
Any help on this project would be greatly appreciated. There don't seem to be many Eos upgraders on any of the Forums
