Was quoted in another thread this morning although there was something about it not containing the manual for a TD27 so it might not go back far enough for all models. Either way Dion's the D21 man he'll know where to get hold of something like manual I'd reckon.
My mechanic will wonder what the hell a D22 engine is doing floating around next to all the big Mercs and Ivecos. And when his offsider find it he'll rip it off for parts to help finance the Patrol so it's all good.
You are right though, I'd rather the Nav was 3 foot wider than more powerful, I love taking up space on the road and annoying impatient tools.
