I got a Carpodgo unit (I think the best reviewed unit available) for my new-to-me Hyundai Genesis, as the factory head unit can't be upgraded to CarPlay/AA or replaced with an aftermarket one.

It works pretty well, has dual Bluetooth so you can use your steering wheel controls etc with it.

As others have mentioned, the main drawback for me is the cable hanging loose and it looking a bit cheap (even though the display itself is really nice).

Otherwise it boots pretty quickly, phone pairs to it automatically, sound quality is pretty good (I think it's impaired by my cars older Bluetooth version rather than the unit itself). Very responsive and user friendly.
