I wanted to share a neat product I just had installed to allow me to listen to music and podcasts from my Android smartphone - the Simple Tranzit USB:

TranzIt USB IS32 - Universal Car Integration Kit for Smartphones, MP3 Players

It allows the connection of a 3.5mm AUX cable from your MP3 player or smartphone to the factory audio system. I had it professionally installed, so I can't comment about that - but it was very cost effective, only $200 installed. I can say it sounds great for both podcasts and music (unlike an older FM transmitter I used with an iPod). I'm using it to connect my LG Optimus Android smartphone to my 2005 X-Type with Navigation. I even had the shop install it where the factory ashtray is and when it's not in use the device and cable are discretely hidden behind the flip up door.

I originally considered the Jaguar ACM module, but balked at the price. I then considered the Parrot Bluetooth kit, as mentioned on the forums, but found the $200-$300 device price quickly ballooned to nearly $600 installed as the Parrot only allows for 4 speakers and all the additional speakers have to be isolated with relays, which adds a number of additional parts and a significantly more time consuming install.

So for anyone looking for another option to connect an MP3 player or smartphone, I highly recommend it!
