Upgrade Touch 2 on Yaris 2017 possibilities

[TheBo]

I have a 2017 Yaris with a Touch 2 without DAP+, Navigation, VGA possibility.
What I understand is that that are options you can plug in with a module..
The prices will not be cheap with my understanding.
Is there a cheap way with universal products to upgrade the system, ore are all modules specific from Toyota?

Own Yaris L hatchback.My radio is t10028, bought Hartman extension box(2014 model/maps), got harnees, back up camera and back up harness. Everything works great, maps or older but work for me. Also bought metal brackets from Toyota to attach the extension box. Also my model did not have cruise, bought 12$ Cruise control switch, just pop off airbag 2 screws then plug in works great also bought new cruise steering wheel cover from Toyota. Found video for radio on YouTube from a Scion FR-S. Good luck.
