Yes, there is dedicated GPS receiver and it works great. I've used it in a variety of settings with excellent results... Walking, in my car (with Waze), and on my boat. GPS is often missing on these little tablets, but it is NOT missing on the Sero 7 Pro.
I've had mine for a couple of weeks, now, and I know the spec list is unbelievable when you look at the price. But, you can believe what you read. I am VERY impressed at what they have for the price! They really do blow any other 7 inch tablet away...
except for the $600 Note 8, but that isn't 7 inch, and the $400 Asus FonePad (not the Padphone... ick!) But both of those are also phones and not available in the US. (The Note 8 you can buy here is the crippled, wifi-only version) And they are three times the price or more.
Yes. The tablet uses both the GPS and WiFi to identify your location.
Yes, the M470BSA does have GPS capability.
