Guide map includes capital of India (5)
I believe the answer is:
pilot
'guide' is the definition.
(pilot can mean a navigator)
'map includes capital of india' is the wordplay.
'map' becomes 'plot' (synonyms).
'includes' is an insertion indicator.
'capital of' suggests taking the first letters.
The initial letter of 'india' is 'i'.
'plot' placed around 'i' is 'PILOT'.
(Other definitions for pilot that I've seen before include "This person can be found in a plane or a boat" , "Person in charge of aircraft" , "air traffic controller?" , "Driver of aircraft" , "Steer, test (scheme)" .)
