Your question, as phrased, is a little unclear. Some here have recommended stereo replacements w/CarPlay but I *think* you're asking about units that are separate from that, and are typically mounted on top of your dash (or to your windshield via a suction cup).

I recently purchased just such a thing. In fact, after doing a fair bit of research (watching several YouTube videos, and making a spreadsheet to chart the features that were important to me, and how the various makes/models stacked up), I ended up buying two different makes/models from Amazon so that I could compare and return the one I liked less (or possibly return both).

As I was writing up my reply to your post, I realized that my post was starting to look like a more detailed review/comparison of the two units, so I switched gears and started to write up two separate reviews of each of the units, but then I had to stop writing to work on some other household priorities, so I saved my first one as a draft. Hopefully I'll have some time tonight to finish those and post them, but I figured I should get back to your thread first, in case you haven't pulled the trigger yet, and can still benefit from some quick advice from me. So here's the short version (again, more detailed "reviews" to follow later):

I bought these two units:

I returned this one:
Imagebon 9.3" CarPlay unit (Amazon link - $220 after coupon)

I kept this one and really like it:
ATOTO P8 7" CarPlay unit (Amazon link - $228 after coupon)
