After seeing the above post I thought I would share my experience of my honda jazz mk 3 ( EX Navi 17 reg) infotainment system.
I've owned the car from new and it's been excellent, that is apart from the infotainment system.
When the car was 18 months old I was sitting in a car park waiting for my wife to return from shopping. Engine switched off , so turned system on to listen to the radio, after about 20 mins the usual warning flashed up on screen " battery protection please start engine" so I started the car, the 3d H logo appears on screen followed by a 2d white logo and spinning circle it went into a boot loop from that point, I tried all of the above fixes to na avail.
Back to Honda dealer, who said it needs an update. Update didn't work. So brand new unit fitted by Honda (thank god it was under warranty) and I'm a happy man again.
About 8 months later Gets into the car after finishing work, starts car
And the boot loop happened ( no on screen warning this time) again. So back to dealer again , new unit is ordered and fitted costing £1500, I'm starting to get annoyed and worried ,now the end of warranty is getting ever closer , and Honda isn't so reliable as I thought, so I phone Honda UK and explain the problem
and my concerns,
honda say leave it with them, 20 mins later honda phone me back saying they are very sorry I've had problems with the car , and would give me another year's full warranty on top of my remaining warranty for peace of mind.
So far 18 months on the new unit is working fine .
But I am still a bit worried about the infotainment system in these cars I don't think they are the best quality, and I think in time more will fail, which is unfortunate because the car is excellent otherwise.
So if you do have problems with the system, raise the issue with Honda UK, I'm sure it's not just me who's had problems with the system.
