Outback Sat Nav

[Lou]

Hi All. 

I posted on here about 7 months ago asking advice on updating my 2014 Outback Sat Nav. After many months I eventually did it and it's been working fine. My problem now is it's stopped working totally, The Pioneer screen comes on then the license agreement screen, press the ok button and I get a hatched screen. The unit then shuts down after about 10 seconds and keeps on doing this. My dealer couldn't sort it and would get back to me. When they did I was told it was out of warranty        ( 6 weeks ) and I would have to pay for a new unit. Although they have a5 year warranty the first 3 covers everything and the last 2 engine and gearbox only. Any ideas what it could be or what course of action anyone would take. 

Cheers
