don't BMW usually have an aux port you can probably add an extension of aux port from the head unit of the bmw.. but will cost you $$$.. most of the standard car head unit that comes with the car do have more ports for you to add stuff.
Has there been any progress on this front? I've got a car pack and it was unusable when I bought it (haven't tried the latest firmware update yet, but I doubt it made an improvement significant enough to be game-changing).
There are two vectors through which such a hack might be implemented:
- Opening up the car pack unit and modifying it to amp it up (e.g. by removing a resistor or something)
- Hacking the firmware and somehow managing to load it onto the car pack unit
It's pretty easy to extend the range of most FM transmitters. Find the antenna wire (if the company wasn't lazy, it's most likely marked), unsolder the wire, solder your own wire (preferably around 32 inches) in place of the old antenna and viola, you're range should be about half a city block.
I'd like to indicate that your information was certainly appreciated, at least before you nuked it. I'm sorry about the double post thing, though them's the rules - you got the warning because of the 4th post. Just make sure to avoid posting consecutively in a thread until a 24 hour interval has passed between posts. This forum has a multi-quote feature; the button's near the normal quote button. It doesn't quite work right though, so a more functional way is just to open the quote page for several different posts in multiple tabs, then collating the quote blocks into one large post. This way, you can quote multiple posts without risking a warning.
After some searching, I think I found the antenna on the circuit card. So I disassembled the unit went to my car and plugged it in and got the same crappy static then I touched where I thought the antenna was and got a good reception from my stereo. I took the circuit card back to my garage and I soldered in the new antenna and I am happy with the results. THE WARNING, TRY THIS AT YOUR OWN RISK AND IS FOR RESEARCH PURPOSES ONLY. I AM NOT LIABLE FOR ANY DAMAGES. Will post pics as soon as I can. Grandrob
