looking for a gps that is easy to use.
because the user is a complete caveman where tech is concerned.

Ton. Would you like to borrow my Wahoo Bolt V1. It's my spare unit but fits your bill perfectly. If you like it then you might want to invest in the V2. Almost same caveman friendly, but with a colour screen and 'point and shoot' option.

Let me know. I can deliver it

Hi Tony,
I’ve got a Garmin Etrex 30. Comes with one on the TalkyToaster topographic shore UK SD cards. Loads soft extras and a nice MYOG handlebar mount.
One of the easiest to use Garmins and in VGC.
Give me a shout if interested?
Adam.

Whole UK Sd card, that should read.
Sorry!
