Hi,
We installed a head unit with a screen that slides in and out. The back was the size of a normal aftermarket car stereo and it only just fitted behind the dash. You also have to be very careful where you position it especially if your installing the additional air vents. There really isn't much room back there at all once you have everything in there. Get your self along to stoneliegh and ask to have a peak under someone's dash.

In regards to the aerial we used one that was a long flat strip that stuck to the underside of the grp. Not sure how good the reception will be on the move but it was ok in the garage.

Can't help with the mirrors as haven't driven ours yet. I'm sure there'll be someone else along soon who can help though.

Think your probably right Steve about the strip aerial. The main use of the unit is a sat nav and reversing camera. I was kinda hoping the only noise that will be required is that of the ls7 behind our heads!! Mmmmmm

To answer your questions in turn:

Yes, mirrors work fine in standard GTR posiition, or can-am style, even at speeed. I have can-am style on my GTR, lowered 80mm since IVA. See pic. What you need to be concerned with is the field of view for IVA. Can am style mirrors on a GTR work fine for IVA at standard height and arguably give a better field of view as they are slightly further out. They also are not impacted by the wing position, being a bit lower that standard GTR mirrors. When I went to IVA, I don't beleive anyone had fitted Can-am mirrors on a GTR before, so I left them standard height, only lowering them subsequently for purely aesthetic reasons. Overall visibility is fine, with you also being able to see directly behind the car.

Double din AV - I did this and space is tight and - as previous comment, you need to work out your vent pipe routes, but I managed to get effectively a flush fit after a few mods to the Din surround and fiddling about. I mainly went for my unit for sat nav capability and camera input (camera useful when reversing. I personally wouldn't bother with 2nd monitor screens - you'll find you use your mirrors to scan traffic behind, not the camera screen.

Regarding aeriels, I went for a flexi rubber 10 inch aeriel, mounted off the bracket in the lower front of the right hand side pod, where Ultima traditionally bolted the brake servo (if I remember correctly). Radio signal is fine (for FM) - and the sound system is useable upto approx 60mph, and certainly ok when in traffic.

have you thought of fitting the standard mirrors in a lower position on the doors??
