Hi all. Just bought a 2nd hand 2013 Toyota Kluger KX-S on Saturday. Have been looking around forums and such to find info on after market kit, specifically speaker with GPS head units, parking sensors and a better reverse camera with park guide lines. Would appreciate it should anyone be able to provide some info on this or point me in the direction of known customisation groups, kinda like what AMG is to Mercedes. Troy.
