Phantom Classic Gen 1 update 750w -1200w

[Simo]

I own a Phantom Classic, no Bluetooth serial ends 3PEK.  I set up the Spark app 1.14.1.3 - here is my question. 

Will this unit upgrade from 750w to 1200w automatically?   
Next it seems that it is also capable of going from 1200w to 2000w on another update.  Am I correct?

Hi, i don't have a devialet speaker yet, but i know what you said is correct. The phantom classic can be updated to the 2000w version. I don't know if the update takes place automatically or if you have to authorize it manually from the app.
Are you happy with classic? Do you feel the need to switch to the gold version?

Best regards
