Looking for instruction on "How to setup gps on my vizio tablet." My understanding was when I bought this it worked just like a Car GPS. It works OK when you have a signal at home , but when you get in your car it locks up.How to I set this up to navigate. Do you have to use bluetooth on you phone? Thanks I didn't see a forum for Gps questions..if there are one please move to where this needs to go. I new and this is my first question. Thanks
