Upgrading Navigation/Audio Player (Citroen C5 2009)

[TodiCroitor]

Hi,
On my old car () I had fitted an Pioneer's AppRadio and I was very happy with that: touch screen and stuff. What are the possibilities upgrading my current R-neg (i think) navigation? I am not looking necessarily for an after market solution but maybe something from the newer car models.
In time I plan to do some upgrades to my car including rear camera, parking sensor... etc and for some of that I would a nav system that would support some of those features.

Is there any system that has for example audio bluetooth streaming?

Thanks!

You need to be aware that there are various revisions of the same audio systems RD4 for example that support different functions. Same for the camera, it wont qork just plugging it in without the right unit. Also with the parking sensors, you need to have the right ECU, as there are several types that support the rear front / rear/ camera modes etc.

Have a look at this index for possible insights and what is involved for some upgrades:
