Bolero replacement options please...

Hi all! 

I've finally bit the bullet and now own a 2014 vrs Estate. There's a fair few things I'd like to change / upgrade! 

First up, it's got an aging bolero (I think) unit. No nav, no Bluetooth etc. 

What's the best option for a simple swap? I've seen xtrons been quoted? Basically I'd like ability to add a camera reversing in future,  car play android so can use Waze etc, stream etc. I'd prefer genuine but it seems that's not that easy. Looking for a plug and play really, I'm NOT DIY confident so either needs to literally be plug n play or reasonable for someone to install. 

I have many other things. So apologies for the posts in the coming weeks, but seems really helpful forum so far so thanks all!
