I have a 2007 Grand Picasso Exclusive with the head unit in the attached image, however I am having trouble identifying the exact model that it is - is anyone able to kindly advise?

Once we know that, what firmware is the latest applicable and how best to get hold of it?

Finally, I'm looking to get bluetooth streaming from my phone working with it - again, what is the best way to do that.

I've been looking around the forums and found loads of different bits and pieces, but it's very confusing and I'm not sure I'm going down the right track - so I'd certainly appreciate any advice you can provide.

Thank you in advance,

It's an RT4/5 basically all they fitted to the C4 until the later variants. You can get the updated maps etc from the link above that the web admin posted.

I needed to know what model it is as I'm having a Parrot kit MKi9200 installed and it doesn't seem to want to work properly, they have used an extra wiring harness with something added to compensate for the standard amp but have no success. Is there a way of getting Bluetooth fitted to these headunits or is it just sim card only or is there a way of fitting the Parrot kit to work with the standard amp?
Many thanks.
