Volvo Sensus System from 2019

Hello Volvo driver, I didn’t regret having switched to Volvo a few years ago, but I corrected the error now. But I would still have a few questions though I have searched the web already, but did not find a real answer. So my Fzg. is a V60 T5 from 2019 I have two questions about the Sensus system. How does the WiFi own Volvo Hotspot function work? I connected my phone with it but it says it can’t be connected. How can I update the Navi card material – and how and where do I see which one is currently installed? I had already contacted a Volvo dealer, and he also confirmed that you can download this on the Volvo homepage car. There is no way to get there for the V60 2 series. And in the Fzg. is only that the file is too large and the button is grayed out anyway….except Baltic & Finland. Thank you for any help and answers – Greeting Tom
