Parrot Asteroid Smart
Best price: £410.87
The Asteroid Smart is good at what it does, but it doesn’t do as much as rival double-DIN units. Rather than mirroring apps, you download them again from the Asteroid Marketplace – this is easy, but we’d prefer to use our own.
Like the AppRadio, this has no front ports, plus no CD slot, but the lack of a drive makes it shallower than usual so it’ll be easy to fit in tight DIN slots.
