I've got a
FRDW/PC-POD for sale (see
discussion of its use in a FEH.) It's just a year old and has been used exclusively in my 2006 Ford Escape Hybrid FWD. I am upgrading to the PC-POD2 (only difference is the ability to still use the iPod's controls; both charge the iPod, are controllable from the stock NAV radio, etc.)
Here's the full specs and info on the item as well as the current RETAIL price:

This absolutely works in '06 FEH w/the 6-disc CD changer under the front passenger seat. It probably works in comparably equipped other model years as well --
Read this thread to determine if this will suit your ride.
PM me here with your best offer before June 10, otherwise it's going up on eBay after that date.
