1, i'd like to fit a sub & amp but there is no output on the back of the radio so i'm going to need a line out convertor, possibly even a 4 channel one (note 3rd option id like to upgrade to)
2, bluetooth device for music & sat nav on my phone, auxiliary (3.5mm jack so other can easily use it) and if possible a usb which will let me play music stored on it through onto the cars head unit.
3, i have an old sony cd changer, if there is any leads that can connect this to the headunit (via using an adaptor for the above or an additional adaptor) then i'd like to do this too. The changer uses BUS leads and i'm not sure if there is anyway of converting these leads to fit an RD3 headunit.
The head unit has a cd option which is something i could opt for but i know these changers are picky at playing anything that isn't a genuine CD (ie copy) & obviously if i can connect my phone to the head unit (via bluetooth) then i won't really need a cd changer, i'm only after fitting this sony unit as it's something i already own so it's basically a case of "it would be nice" if i could use it but finding some way of connecting the devices together is borderline impossible i think.

I believe from a few posts i've picked up on Yatour may provide an option for bluetooth but they are in germany & their ebay website is all in german, something i don't speak. From what i can tell these plug into where a genuine cd changer plug would go but i'm guessing the head unit/car will need configuring & i might even need the transponder code which didn't come with the car. (i'll get this at some point soon anyway as i'm likely to need it in future).
If anyone one has ideas on brands, devices etc i'd appreciate it
