After it was jump started 2 months ago, the following things stopped working: map lights, clock, radio, cig lighter, keyless entry, overhead lamp. I’ve been told it needs a computer diagnostic scan, around $75 - $99 just to see whats wrong. Will have that done soon (haven’t had the $). Does anyone know what is wrong and what it will probably cost to have fixed/replaced or whatever? Thank you 
Have you checked all of your fuses? I would always start there since that is the cheapest fix (replacing a blown fuse).
Map lights, dome lamp are probably on the same circuit
Radio, clock and cigarette lighter are probably on the same circuit
So you may just have 2 blown fuses
