Adding Optional extras to 2009 c5 exclusive

[Diakatarnis]

Hi I've just got myself a nice C5 exclusive 2009, and was wondering how easy and what I would need to install the following upgrades:

Navigation system (is it called mynav or something like that ? )

Heated seats

Timed heating / defrost?

Bluetooth (is this part of the navidrive system?)

Lane change detection.

Not sure which ones are feasible but I can't seem to find much info online and the navigation system seems to have so many models i have no idea where to start.

The sat nav was Navi-drive, then was updated to "Myway". As far as I know, you cannot add a sat nav as the whole fascia is different.
Bluetooth is included in later cars, I'm not sure from which year. If you have the slot to the right of the radio for a sim card, you cannot add blue tooth.
By Timed heating, if you mean a diesel pre-heater, then probably not, unless the stuff is already on the car. Lane change detection I don't know, but I suspect most "packs" or "extras" were added at manufacture, according to the customers requirements.
Heated electric seats should be manageable, but at a cost, again if the wiring is in situ.
Afraid that you will probably have to enjoy the car as it is, unless money is no object.

If you do a google search you can find an after market sat nav that includes a new screen and trim. It looks neat in pictures but I would want to see what happens with the usual Citroen messages that would normally be on the screen.

I think after having a look around a lot of the upgrades may be too expensive, however upgrading the RD4 to RNEG doesnt seem too hard, but i cant find anyone who supplies the facia

There other option would be to find a breakers and get the facia from a +NAV C5 which should have the same inside trim, and then use that, but can I find a local breakers with a newer C5 .... not a chance

Any suggestions? I'm in Chesham in Buckinghamshire.
