HF Radio in Navara How to fit.

Gday all,, Have just traded up to a ST-R Navara duel cab and need to fit my HF radio into it.
As with all modern 4x4s there is very limited space to fit anything around the dash. Have had a UHF fitted in the slot above the CD and can fit the HF radio behind the rear seat. Its the remote head and speaker that will be the problem so maybe someone out there has already fitted one in thier Navara. The only place I can think of is at the rear of the centre console. It would be in the back but you hardly ever use the HF when traveling anyway and its not often anyone will be in the back. The radio is a Barret 250 R any ideas would be appreciated.
