We'll see what Adrianlle says about the Pioneer.
I've got a Sony AX3005. Easy enough to fit with an ISO wire from Halfords. Reverse camera plugged into it, a microphone for the hands free and a DAB aerial.
If you're not used to japanese cars you may be surprised how much you have to dismantle to change it - I'm used to using two radio keys then sliding the old headunit out and new one in - but not here! 4 million screws later, and you're there. Its not that bad really, but just be prepared the first time you see it!
Sony didn't QUITE fit the gap left by my original Toyota radio - i used the cover from a black exercise book from Tescos to go around the gap - perfect.
Would I get it again? It works well ; DAB is good and I use it for Android Auto so I can get google maps / waze / YT music etc. It has some physical buttons that I like for volume, next/previous channel and to turn the screen off - that was important to me. The touchscreen isn't quite as responsive as I'd like - its fine, but its not an Ipad. You can upgrade the firmware which is good; I dont like the fact you cant upload your own gif/png/whatever for the background - I requested that feature 2 years ago and they havent bothered.
I'd look around and see whats available now, technology has probably improved since I bought it - but its a solid option.
