Hi,Thank you for using Just Answer my name is ***** ***** I will help with your question. I have had a look and it seems that a firmware upgrade is needed I will continue to search for the firmware and I will be in contact when I find it, hopefully tomorrow.Carl
Hi,I am very sorry but I am unable to find the firmware. I have spoke to several people today about the firmware and I have mixed advice from them, most of the people I spoke to don't think it is possible to get an English firmware for your head unit because according to some of them it was only released in Japan. It was suggested to me that maybe Toyota will be able help, I don't know if you have a local friendly dealer ship that you could ask, my honest opinion is that they will say it is not possible but I would give it a go.I am very sorry I could not help I normally don't have too much trouble getting firmware for head units but this time I have no luck.Carl
I will leave the question open for a bit and I will continue to ask around and see what I can find. Where about in UK are you?
