Found a few pages here worth reading for further clarification:
http://pdfserv.datasheetpro.net/Broa...325-PB00-R.pdf -- If you look at the visual layout of the chip, the FM receiver doesn't have a direct connection to the host device but passes through the Bluetooth section before it reaches the host. So since the bluetooth on the TP2 works, so should the FM tuner. The only possible explanations at this rate are a) software/SPL limitations or lockouts or b) The antenna lead on the FM side of the chip is disconnected so it won't pick up anything beyond a few feet.
Still no luck finding a true datasheet with a pinout though.
