[OZAPRS] Need a hand

I've just looked at my X-Trail and I think I've lost any enthusiasm I 
had for installing radios, hi. I think the engine block was poured in situ!

The main frame of the vehicle - subframe, floor pan, roof, firewall and 
door frames - seems to be a welded mass of metal to which mudguards, 
bonnet, doors, etc are bolted, so any bolts attaching components to the 
sub-frame could be a possibility. A "Z" bracket coming out from under 
the bonnet could possibly utilise one of the mudguard mounting bolts. A 
magbase on the edge of the bonnet could be earthed via a short lead to a 
mudguard mount or the bonnet hinge mount. Most bonnets are not purposely 
earthed so heavy(ish) straps (RG213 braid, e.g.) around the hinges could 
be beneficial. A couple of possibilities there, but this is just one 
specific vehicle.

My days of crawling over and under vehicles to install radios ended a 
long time ago; these days I'm the wrong shape for crawling under, and 
multi-focal spectacles don't work well upside down under a dash.
