Navall 1 has gone dead

timspencer · 4th May 2017, 16:49

Mt ZT has a Navall 1 system fitted (I think) which was working fine....

The car had a slightly low battery which needed a jump start.

Ever since then (it may be a coincidence) I have a black screen of death which doesn't work at all.

Blown fuse perhaps?

Do the side buttons light up when you put the car lights on ?

I'll give that a try later and let you know thanks.

Nope nothing.

Time to check those fuses then.

Might be worth pressing the reset button on the unit as well, see if that springs it into life

Will do, where is the reset button?

Under the right hand knob, you'll need a paperclip or similar to press it

Apart from the fuses in the car, the unit itself has a 15 amp mini blade fuse mounted behind the loom so worth checking that as well.

Before delving any deeper disconnect the car battery for two or three minutes and it may very well spring back to life. One of my Navall 1 units dos this every now and then. Battery disconnect sorts mine.

Worth a try
