Hmm. Since doing this the nanocom has worked fine... with one caveat. It frequently won't power up at all. I suspect it's either the diagnostic port on the car that has a dodgy terminal, or it's the lead to the nanocom itself. Given the use it's had I doubt that one.
So, I've been trying to clean the terminals etc, which is awkward with my knees. Anyway, it pwered up, but has gone back to "firmware disk not found" Ok, been here before and can fix that.

Would it be a reasonable assumption that the issues may be being caused by the diagnostic port or the wiring leading to it? Is it possible to re-route this wiring. I don't mean physically, I can do that with a lot of swearing, but electrically can I screw it up? My port has never been secured properly to the under dash panel as it's damaged. I guess I could repair that.

Anyway, digging out the laptop with windoze on it. Guess I'll jump into RAVE while I'm at it.

I imagine it would be, try using your hands.

One way to work this out is to use the USB cable.
IIRC the nanocom came with a USB cable in the box. Should do both data and power.
You can just power up the nanocom using the USB cable alone, obviously can't communicate to D2 tho, but this is just a test to see if it starts up 'every time'.

The power port only requires 500mA, so I assume that same power requirement from USB to start it up too?
Alternative is to connect a power supply of some type to the power port too.
Technically! ... the nanocom quick setup guide does specify to run a 12v 500mA power to the power port, and not just rely on the OBD cables' power alone.
In saying that tho, other than one time, I've never used the power port, and always just run off the OBD. Only time I used power port was when flashing updated map to ECU, where I also had the car on a power supply to be sure nothing randomly shut down.

Thanks Ian. You're a great help, as usual....

Thanks. Yes, the nanocom works as expected when plugged in to the USB. Also, this nano, my second, has hardly been used so it's main cable should be fine. Yes, just because it's new etc.

Just to follow up. I'm pretty sure it's the plug in the car, as it's not secured to the dash, and was dangling so I have prolly trodden on it. I now have a new plug and bracket. So I'll get that installed and see what's wot.

Sigh, with my back injury I was hoping my days of crawling around under dashboards were over. Is there any reason why I can't extend the wires to the plug so I can get at it easier?

Could get an extension cable? Try jaycar.com.au
