I believe the blackvue overheating issues was only on the pre-2014 higher spec models with built in GPS. The 3500-FHD model that I use has optional external GPS functions and is a 2014 model, so no overheating reported to my knowledge
Funnily enough after I posted that I found one of the (short) clips in the card would not play, and the update claims that they have added some improvements to video processing. So I thought I would apply it seemed very easy to do. I suspect this may be because of a power-off mid processing issue. I just downloaded, copied the files to the card, very easy
It worked perfectly this morning, it spoke to me, telling me it was updating the firmware, to wait and to ensure I did not power off until completed. It was a nice touch, and then I started on my way to work. It then told me it had completed, and was performing a reboot. It then started up as it would any other day.
I think that is the difference between the cheaper models and the likes of blackvue, whilst the feature set is comparable, the ease of use/reliability/installation/support is just miles ahead. I figure it is worth paying for!
I am actually considering buying another for rear use, found the same model I have from ebay for sub £100, so very tempting
