Driver's guide took a seat and reversed motor home (3,3)
I believe the answer is:
sat nav
'driver's guide' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'took a seat and reversed motor home' is the wordplay.
'took a seat' becomes 'sat' (I've seen this before).
'and' means one lot of letters go next to another.
'reversed motor home' becomes 'nav' (I can't explain this - if you can you should believe this answer much more).
'sat'+'nav'='SAT-NAV'
Can you help me to learn more?
(Other definitions for sat nav that I've seen before include "Guidance system" , "Aid" , "Direction-finding equipment" .)
