Am planning on installing my XM XpressRC satellite radio in my 08 Limited. Will be connecting it using the FM Direct Adapter. I am also interested in using one of the "Vehicle Specific Dash Mounts" to mount it up on the dash next to radio. I am intersted in this, but am nervous about spending $50 for something that won't work well. Anyone using something like this for their Sat radio or Ipod? Does it work well with the Ford dash?
