Driver Hours feedback

Brilliant Muckles Thank you very helpful.

Can I ask when you change a Digi Tachograph to rest can you turn ignition on and off Ie to turn on radio or heater or leave the cab ? Hope this makes sense !
Also is there an upto date Digi simulator to practice on as I am going back to Hgv driving and not sure how to make manual entries at start of day for walk round checks and when you finish I believe you have to add 10 minutes or so for unloading ,paperwork ?

Thanks in advance
