Lively or Not

Cross-posted from the electronics forum....
I'm looking at buying either Lezyne's Macro or Mega GPS computer and have a few very specific questions for any users of Lezyne's Y10 products. ...Lezyne designated their first year's GPS models as Y9 and their second year's lineup as Y10... Also, I know there are significant differences between the 1st version of Lezyne Ally and the current 2nd version, so please note if you're using the first version.

1. If you copy a route to the GPS from the phone, can you begin navigating in the middle of the route?
2. Is a data connection required to copy a TCX file from the phone to the gps? I'm unclear whether importing TCX routes requires an active connection to the Lezyne Root website, or whether you can import the route from a file on your phone using the Ally app.
3. Will the unit record and/or display speed (based on GPS) if you don't connect any sensors?
4. If the GPS has a location fix and your phone is connected via Bluetooth, can you view your current location on a map within the Lezyne Ally V2 app (assuming you've downloaded offline maps)?
5. Does the GPS offer audio alerts for upcoming turns when using navigation?

Thanks in advance!
