True Position ISO 2768-m

I am currently programming a job from drawing with a hole with no true position specified, it has boxed dimensions which would imply a true position. I've notified the customer to ask what the true position would be and they said I should be able to get the true position from the ISO Spec?

To my knowledge the ISO specification used being ISO 2768-m does not specify a true position to use for boxed dimensions with no positional tolerance, this is usually illustrated on the drawing in a tolerance frame around the hole call out? I'm looking to reply with words to that effect, am I right to say this?

I've checked the standard and I can't see anything on this, any advice would be greatly appreciated

I'm just assigning a 0.6mm true position tolerance to holes. It seems like a reasonable number in comparison to M and K, and I'm not seeing anything referencing position in any of these documents...position and symmetry are rather similar when it comes to a hole in a central location
