subjective I suppose but your software is waay behind the current so it would probably be worth updating.
personally I preferred the look of version 4.20.......
but version 5 certainly adds extras
jatt420 On the box Show Speed Limit, it should state either YES or NO. To change from one to the other, click on the box, highlight yes or no then done. For YES it will then show; Show Speed Limit Yes. I would guess that not every road on every map has been enabled so it could be that you get on some but not necessarily on all maps
