Hi guys very new to this forum so bare with me as i navigate through how things work. I Have recently purchased a D22 05 Navara and putting in an outback centre console. I have read the instructions all seems straight forward, however im also installing a GME 4400 UHF is there any reason why i cant use the existing map reader supply for the supply of the UHF if i wire in the inline fuse. Also i have an ARB bull bar were is the best place to mount my GME 6.6db aerial and any advice how.
