Need some advice

So it’s been a while since i was last on here…have been doing a lot of agency work here and there which was great untill it kinda went dry for me…but everything is working out well

so here’s what i’m hoping you guys could give any kind of advice about.

had an interview today for recovery technician job (breakdown recovery if you prefer) and was offered the job full time which sounds awesome and quite challenging for me, i’m doing a few days buddy training and when the next one comes up going for an intensive course through company on how to do it but i am slightly worried some things but my major concern is

I’m not fluent in motorway junction numbers and locations except m5 so when a call comes in is there an easier way to find it on satnav other than googling somewhere close to it and hoping? I do have and know how to read a map but memory of a fish makes it harder to use

or maybe i could just get some general advice on this kind of work. its not just breakdowns but also things like crash’s and other things any help would be appreciated
