GPS has nothing to do with the local mobile phone network (GSM) and your tomtom is not governed by GSM either
GPS = Global Positioning System
GSM = Global System for Mobile Communications
Global for GPS meaning all over the globe which includes all of Lincolnshire 
if you had googled it ( novel I know in your case ) you would find that the americans put over a dozen satellites surrounding the earth in an orbit such that a gps device "locks on" to say 4 or more satellites and then works out your position on the earth, I believe they may have done this BEFORE mobile phones were introduced, especially digital mobile phones like your S3
so your satnav uses a gps positioning system internally, locks onto the signals from 4 or more satellites and triangulates where you are on the earth and then uses maps to display this to you, some gps devices just give you the bearing like your longitude and latitude
this system works even if you are in the middle of Canada or the Atlantic ocean and nowhere near any cellphone towers !!
you can read about it using this wiki here
Code:

and they say a little knowledge is dangerous
Code:
he Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather conditions,
anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.
[1] The system provides critical capabilities to military, civil and commercial users around the world.
It is maintained by the United States government and is freely accessible to anyone with a GPS receiver.
The GPS project was developed in 1973 to overcome the limitations of previous navigation systems,
[2] integrating ideas from several predecessors, including a number of classified engineering design studies from the 1960s.
GPS was created and realized by the U.S. Department of Defense (DoD)
and was originally run with 24 satellites.
It became fully operational in 1995
The space segment is composed of 24 to 32 satellites in medium Earth orbit
------------------------------------------------------
so a good theory but totally flawed when you realise how the GPS system works
also the mobile phone network was an@logue back in 1995 - not digital
its like saying you get sly from your local tv transmitter , which we all know is false as it comes from satellites in geostationary orbit at 28.2e over the equator
----------------------------------
cellular mobile phone technology can be read about using this wiki

GSM = Global System for Mobile Communications

you really need to learn the difference between all these different systems and acronyms, also learn how they all apply to your different devices too
-----------------------------------
so if your tomtom start 25 is failing to lock onto 4 or more GPS sats , and your mobile phone is doing the same, maybe its because you are indoors or have some local interference causing issues, could even be the same local interference that stops you obtaining man utd tv on 10e using biss - who knows ?
also, some of your efforts on this have involved copying files and folders to various places, whereas the actual details were
copy and paste the tomtom folder to the root of the android device OR the root of the SDcard
copy and paste the apk hack file to either the root of the android device OR to the root of the SDcard
then run the apk file using a file manager or file explorer
