I was looking into this and noting not long ago fitted canbus enabled towbar module ( for my O3) and also fitted cruise on my fabia vrs -
so I'd imagine I'm well competent enough with the right guidance instructions at least.....

This Citigo is the model with the mobile stand not navs (2017) and I'm a little unclear if a specific model required but I did see something suggesting all from 2012 up to the e model which this is not.
I'm wondering if installation is common and follows this guide for the UP although I'm not certain about that. (part I have seen suggested = 1S0054630 with 1S0919475 control module) ?

Also If going to the effort it would be really cool to have the proper enabled beep lines show up on the ( still standard) radio also though, less keen on aftermarket. Anyone know if it works?
I wonder if it matter if you have the Navigon/Garmin or none like this car I originally bought which takes mobile bracket/charging and apps instead.

Thanks

 

We've fitted parking genuine sensors and reversing camera to a couple of Up! now and it's not the worst job in the world 

 

If you send me a message with your reg I can tell you what parts are correct
