1. if its possible to purchase a gps receiver, connect it to the headunit, and install software onto my headunit so i can use it as a sat nav? if so, any recommendations?
If your headunit supports it, there may be a GPS unit available from the manufacturer. Expect sticker shock.
You will not be able to purchase a USB GPS receiver and make it work with your headunit. Your headunit
probably has no means of reading a data CD, so loading any software would be right out, as well.
Besides, the software will be specifically for PC, Mac or Linux, and I'm certain your headunit is none of those.

2. if its possible to install the software so that i dont have to keep a cd in the headunit and can have music cd's in there instead
See #1.

3. if its possible to have music playing through my speakers whilst im on the sat function simulteaneously?
This would depend on the functionality of a compatible GPS unit for your headunit, assuming one exists.

4. if i can install a new peice of software onto the headunit which would improve usability and aesthetics?
No.

5. or if i could install car pc software on the headunit or would i need an actual car computer.
No. You would need a full-on PC.

i realise to some these are the most stupidest of questions, but we all have to start somewhere right?
Yup.
