Hello all! For all the X-Type owners who still have a cassette deck and looking for the best way to intergrate your iPod/iPhone on the cheap - check this device out:

Amazon.com: iDeck Integrated Car Cassette Adapter for iPod (Certified "Made for iPod"): Electronics

I bought this for the X last week and it works pretty well. The sound is transfered from the iPhone dock not the headphone jack so you get close to CD quality sound. It also comes with a cigarette lighter power cord and AUX out so you could connect other devices to it (ie. Tom Tom navigation) I picked it up off eBay for $30, so its far more cost efficient than the ACM.
