Fiat Uconnect tomtom update

Hi i have an Abarth 595 with the following nav unit installed:-

Continental Fiat 312 7" VP2 emea DAB NAV running software version 23.02.41.16

The TOMTOM serial number is SV3089H00380 running version 14800.3249884.4217

As Fiat Uconnect was discontinued a few years ago there is no way of updating the maps except by going to Mopar, and for some reason there website do not recognise my vin number, and then tell me to go to your local dealer, who then ask for £250! (in the UK anyway)

What i am wanting to do is update the maps, and hopefully find some way of updating speed camera location on a semi regular basis,

I have done a fair amount of research and found the Uconnect 7" is totally different from the 5" and was designed by continental, and when looking at the serial number code list SV is not even there! so i have no clue as to where i even start looking into what maps ect i need to update this

So, im hoping some of you knowledgable folk could point me in the right direction as to where i should start looking!

Many thanks!
