Nissan Qashqai j11 2016 aftermarket stereo

[nckslater]

Hi all, 

I have just bought a Qashqai J11 2016 and I would like to put in an aftermarket stereo system to use Android Auto and possibly put in a rear parking camera.

I have seen the Xtrons PST10XTN advertised as Nissan specific but unsure if there is something better. My Qashqai has a standard stereo. I don't really want to spend more than €500 on the stereo and I live in Spain. 

Any recommendations? What have people installed in their Qashqai's. 

Thanks
