Crossword Genius

By the way, it will guide you (4,3)

I believe the answer is:

road map

I'm a little stuck... Click here to teach me more about this clue!

'guide you' is the definition.
'road map' can be an answer for 'guide' (I've seen this before). I'm not certain of the 'you' bit.

'by the way it will' is the wordplay.
I cannot really understand how this works, but
'way' could be 'road' (road is a kind of way) and 'road' is present in the answer.
The remaining letters 'map' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for road map that I've seen before include "Guide" , "Document detailing route to an end" , "One shows the way" , "Driver's chart showing routes" , "What may help one get around" .)
