Overall, it is a good GPS.We all use our smartphones, but there are still places where we don't get signals, and it is nice to save our phone battery for entertainment.I only paid 50 for this unit, and I can give 4.5 stars. However, I gave 3 stars for anyone who's considering paying Amazon price.Pros.- You can use your finger to zoom in and zoom out. Its touchscreen is pretty responsive.- Detailed instructions on directions (turn on next stop light, upcoming school zones, speed camera, etc.), I personally think this one is a little more detailed than apps when it comes on explaining turning lanes and such.- It comes with lifetime map updates - of course, it may not be as up-to-date as Google Maps/Waze, but at least you won't have to pay for it.- Voice command function.Cons.- Live Traffic Data: so, it comes with live traffic data, but what it doesn't tell you is, it is not offered in ALL areas. They offer traffic data via Here Real Time traffic, so if you're getting this because of traffic data, make sure to check the coverage area before you buy the unit.Alternatively, you can connect the unit with your phone via bluetooth and use ""Smartphone Link"" app to get live traffic data, which in turn will use your mobile plan data. I found it when I connect it this way, when I get a call, the unit will let me pick up. When I get a text, it will display the message on the device. BUT, it won't let me text back. There is no voice command to text back. (It could be my phone, but my phone doesn't listen to its regular voice command functions when it's connected to Bluetooth - so GPS voice command function triumphs.).So, because I live in a city where they don't have live traffic data coverage, I end up using my phone more.It is a solid unit. If you want more functions, you may look at their upgraded version, DriveAssist, with Dashcam attached. Regardless, keep in mind their live traffic has its limits.
