Me?

I don't have to worry about lugging around a GPS device plus a cell phone plus a teletype or whatever else you must carry around. All I have to do is carry around one slim device. That Tom Tom isn't very slim... I suppose you COULD just leave it in the vehicle but that's just asking for trouble. I mean, IF there are thieves that still take stuff like that.

That, is funny. Great visual to say the least!

I know it's a 2 year old article; but it's a pretty interesting piece about Infinite Skyz

On a phone if you loose internet (4G for example) you loose GPS also.

You should not lose your GPS functionality, the two 4G and GPS have nothing to do with each other. What you might lose is your map unless your phone downloaded the map data beforehand. I use my phone for directions all the time without using data. I just download the map information ahead of time over WiFi. When I was visiting relatives in upper NY state my phone had no service at all but lead me right to their door without any issue. I knew I had no coverage there and download the map info for the area before I went.

I just use a paper map.......

I like and can thankfully read a paper map. I don't know how familiar you are with the ADC brand maps which had fantastic grid coordinates. I am a delivery driver of a pizzas for a national chain and I use Google Maps. I have it set to a terrain mode, which makes my map lifelike, but the system also gives me options on routes, displays traffic issues (delays) with different colors, and also will re-route me due to closures.

I won't be getting the infinite skyz system when i eventually get my Elio, the thing that is piquing my interest though is the automatic transmission upgrade from a manual, and a upgraded stereo system

It depends on the GPS capabilities of your device. Some GPS systems depend on what is known as "AGPS", or "Assisted GPS". This is a method in which your device's data connection is used to retrieve some precalculated positional data (known as the "ephemerides and the almanac"), rather than retrieve it from the satellite signal itself. (Related trivia: the GPS satellite signal data rate is only 50 bit/s!) Most cell phones and other devices that have data connections will use AGPS to download this data via your data connection, when it is available. If it isn't, the time to first fix may be anywhere from 30-40 seconds to nearly 10 minutes, if the GPS signal is particularly poor. Note that download AGPS data is not specific to 4G. Any data connection will work, even wifi.

Exactly how your device operates without a data connection will depend on your specific device: some work just fine, others don't work at all.

https://en.wikipedia.org/wiki/Assisted_GPS
"A mobile (cell phone, smart phone) device with just an L1 front-end radio receiver and no GPS acquisition, tracking, and positioning engine only works when it has an internet connection to an ISP/CNP where the position fix is calculated offboard the device itself. It doesn't work in areas with no coverage or internet link (or nearby BTS towers, in the case on CNP service coverage area)."

Most phones use AGPS for start up, it helps cut down the time needed for acquiring your first position and downloading satellite info. Without this it can take up to 15 minutes to get an accurate fix. They also use it because it provides additional information to provide a more accurate position. Not to mention some phones also use Glonass to help find location. I used to work in the radio navigation field when I was in the Coast Guard. I worked on LORAN, SATNav, Omega, DGPS and Radio beacons such as TACAN. I try and keep up on this stuff I also and hoping that eLORAN will be brought back because GPS is far to easy to spoof or jam.

I'm good with how a GPS works. My question was directed more towards if it were to work in the manner of a Garmin or Tom Tom were you purchase upgrades, or a smart phone where maps are streamed.

On a phone if you loose internet (4G for example) you loose GPS also.

As for the term 'subscription'... you can read that as subscription, or having to purchase a phone number via third party cell provider, or any other non-pre-existing expense to make it work. Matters not to whom the cash register tolls.

Not so true. You can use Google Maps without a phone connection. You go to the app while on wifi and download the map area you want (without using cell connection). Then, while driving, your phone doesn't have to download the map as you go and it simply uses the info from the gps receiver to show you the right spot on the already downloaded ap. It's pretty cool and keeps the phone cool as well since it isn't trying to download maps constantly.
