The problem is that a stand alone Sat nav will always be that, even with software updates it will at some point not be able to keep up with tech or features as it moves on, at that point you'd need to buy another stand alone device. I suppose this will happen with Chigee, but probably to a lesser extent. I'm upgrading the Chigee AIO 5 after only 1 year but I believe that a 6 inch screen removable unit is probably the sweet spot for me, and will probably last a few more years, the sat nav that I use it for, will keep up to date through the phone I use. And I have the option to use different Sat Nav apps if I feel the need. I normally use MRA but sometimes use Waze as it uses crowdsourced data.
Of course, we can all make the choices to suit what we use these things for.
