This is a spare Sirius satellite radio receiver module that will plug directly into the factory wiring. Part# 8E0 035 593 H. This "revision H" module has the newer-style single input lead, but can easily be installed in older model cars by using a splitter. Will work in many different Audi & VW models (do a search for a fitment guide, there is a ton of info out there). Works fine, I just don't need it since I switched to an XM module.

$55 SHIPPED (if you shop around, this is a great price. I'm just sick of it sitting on my shelf taking up space)
