I have a 2016 Twingo and would really like to install the RLink multi-media and Sat Nav. Are there any for sale out there? Also, is the wiring looms already in place or would I have to install the separate antenna for the Sat Nav etc.
Have a look on eBay. There are a couple of breakers on there that have listed the parts you need – dashboard surround and head unit. I don't know if you'll need a new loom, but it wouldn't surprise me if you did. Alas, I've not seen one listed.
