Hi I am resurrecting a Garmin 265W I used to use. It has software version 7.6 I want to know if the following is possible
1 Have speeding alerts if over speed limit
2 Have larger text on camera alerts or different box
3 Change the size of the camera alert box when watching speedo so you can still see speedo
4 Make the speed limit indicator larger.

I am reasonably computer literate but no expert. Hope someone can direct me in right direction
