The edification is - you are gravely misinformed.
You will not find a smart phone without a GPS chip that I'm aware of. It is basic to functionality ....it requires no network, no towers no zilch except power and open sky to see the satellite plus a map that interprets the signal as there are few of us could translate raw coordinates to useful nav data.
You seem to have a lot of knowledge on this subject. I love my Garmin as it is a stand alone unit that will function like it currently does . . . forever. There will be no additional costs . . . ever.
It would be cool if you could do a write up for the rest of us. Whether it is one sentence or many pages on how to use your cell phone like a GPS and keep costs to zero or close to it.
The biggest concern most of us have is the cost. With a standalone GPS there is no monthly charge. I cringe at the thought of my already expensive monthly cell phone plan creeping upward if I have the map on all the time and constantly reading data. Maybe I don't understand this as well as I should. This is where you come in. My new Garmin Nuvi cost like $800 or whatever. But again it is a one time cost. If it is preferred I get a second phone, is that going to cost me $200 for the phone and $50 a month for service? If so, I am already at that same $800 price point and going into the second year I start to lose money.
1) Should a person buy a second phone? What basic plan and apps would I need to get this second phone to function "just like a gps?"
2) Use a single phone for everything? Which method do you prefer?
What I like about my Garmin Nuvi is that I DON'T HAVE to updated anything; ever. Yes there are map updates but I don't have to get them. With anything software I have used in the past (computers and cell phones specifically) I have been in the situation where where I get an iOS update and then my five apps I need to navigate each need an update or the system fails. Does this make sense?
I am very tech savvy and don't like not having the knowledge you do. I guess I have always figured that my cell phone uses data all the time. Maybe you could also tell us which settings to disable so you are never using data. Turning off wi-fi is actually a bad thing right? Wifi networks are free and prevent me from using data. But to me that means I need a wifi password for each network I pass in and out of.
Again, a quick write up would be totally cool of you to do.
