Sat Nav Not Working

[Nashy]

My Dad has a 2002 Avensis and the Sat Nav isn't coming on on the display, therefore it is unusable.

I think it's a power supply problem but I'm not 100% sure.

It scrolls throught the MPG, e.t.c. but doesn't bring up the option to start the Sat Nav.

Can anyone help me get this problem sorted out for him?

I have attached photo's of the head unit incase it helps.

Cheers,

Aaron.

Is there a nav cd player fitted in the boot and if so is there a nav CD in the player?

Yes there is and the disc is installed but it won't eject it.

Sounds like a power supply issue to the nav cd player

That's what I thought ... where are the fuses e.t.c.? Any Ideas?
