got a pretty stock interior 03 taco, no map lights but a bulge in the headliner where i assume they would go. would like to mount an external temp gauge. is there a ext temp unit from a runner overhead that would fit? rear view mirror with temp looks pricey, as does the hilux surf FM--if i could find one. wish there was a digital that went tandem with the clock. any other ideas? search was any help this time. thanks.
