Thought I'd write up improving the factory E46 10 speaker audio system.
I'm going down the intergation with the factory system route which is $$$ debatable when you consider what a Dynavin can do and how easy it be to put a couple of amps off the back. I'm doing this as a techincal challenge as I work in IT communications and for my sins Manage staff rather than do much of hands on these days.

I brought a freeview terrestrial tuner kit for the BMW TV module www.pibus.info . I hate having a module that didn't work. Use to watch TV in the car whilst parked up when waiting for the wife to finish work. Not into driving and TV , but its handy to have the audio only sometimes.
I decided not to go with the USB input for playing media or the ir input. The TV module is still controlled from board monitor.
