Has anyone in the MD/DC/VA area gotten XM installed on a 2006 Prius with the Nav System? I called a dealer a bit ago and they're quoting about $800 for parts/labor. That tells me they don't know what to order. Also says I'd be their first, which I'd rather avoid. Another place said they sublet such things. If anyone's had luck getting it installed at a dealer, could you post which dealer? Thanks in advance.
