Depends on your bike and if you have room for installation....and possibly if you got relatively secure parking.

Most people would just get an android nav screen. They have come down significantly in price and they bring much more than just a dash cam. Some units now will come with TPMS as well.

If you ride a small bike lacking mounting points or dont want the extra screen to be too conspicuous, then get the standalone dash cams, but nowadays, there isn't a significant price difference between the 2.
