Subaru Forester 2019/2020 driving routes eg. connect to MyDrive / avoid jams behaviour / Updating

I got three major things that I want yo know about the build in TomTom of my new forester since there is not much information about that. I love tomtom's but there is lack of information (or I haven't found it yet) about these things.
1) Is it possible to send routes/places/tracks to Subaru's buildin TomTom - this would make my life much more easy when planning routes.. Especially when riding routes. As far as my knowlegde goes it's not possible to upload tracks..
2) How does the Build-In TomTom update it's traffic information - and how frequent? I mean - a road nearby is block for a week. My Go 5000 sees it, Google Map sees it but the build-in does not.
3) How do I update de Firmware ?? - How can I check which version it is running and what map versions there are - (I already figured out how to update but can't figure out how to see the versions)
Regards

I paid for the Touring model just to get the Navi which is not cheap.
Then I discover that there are NO VERBAL ALERTS, Subaru tell me I need to look at the screen for the icon to be displayed as this is for safe driving. How can anyone drive safely looking at a screen is beyond me.
It does not connect to MyDrive or anything else that would allow for tracks etc to be uploaded to.
Subaru state that they GUARANTEE the latest maps, BUT, they update them once a year and only over three years giving THREE updates. Whereas TomTom update every quarter = 12 updates over three years.
I have owned many vehicles, however, the Subaru navi system that uses TomTom is a scam, it's not fit for purpose in that it's unsafe to keep looking at a screen for alerts!
It may be different for other countries, I am in Australia.
I managed to figure out, with help of my dealer, how to upgrade the firmware but they have obvious no answers about the first 2 points. Since I do not android car a lot (google-map works but half the screen is wasted by a directions panel which i never use.. I takes less then a second to see where you need to go instead of reading it
The TomTom maps are useless. My home address...on a street built 3+ years ago...doesn't show up on the Subaru Maps. HOWEVER, when I go "online"....ALL the streets in my neighborhood are present in TomTom's current maps.
How is it possible for TomTom to NOT have the most current Map Version installed in BRAND NEW cars????
I've contacted Subaru Support and they say there is nothing they can do "until TomTom releases a new update". What???? The "map" in the new car is 3 years old!!
I've been forced to use Google Maps with Android Auto. Google Map is current...and, doesn't cost $65 per year. Ditto that for my Garmin GPS. It has Lifetime Maps and Traffic.
I'm trying to figure out Item 1) for my 2021 Outback XT with the 11.6" screen. May as well plan routes in Google or Apple Maps. - the Nav System is pretty useless if you have to sit in the car to plan a multi day route, especially if you want to do specific drives on specific roads.
