Sat Nav Tyranny

Hmm, I have just remembered why I hate updating my sat nav.  Not only do I have to keep the app open, come what may,  it also takes a hell of a time to download and update. 

This time the download started off  with 27 minutes to go. I looked in on progress regularly.  Then...... ***!!!
The screensaver and sleep mode had kicked in.

• So - the machine is now set never to go into standby in  any shape or form.

• "Do not disconnect your device" I am commanded. 

• At least it did not close down and corrupt the satnav, thank goodness.

• There are now 37 minutes to go.  Thirty-seven!

• Where did the extra ten minutes come from and why? Grrrrr...

I'm creeping off, trusting the whole thing does what it should do without continuing intensive care from me.
