Touch 2 go USB issues

[Old chippy]

Hi knowledgeable people, 

I have an issue with my Touch 2 go multimedia system. I have purchase the maps upgrade and downloaded to a USB memory stick as advised on the web site. My issue is that when I plug in to the USB socket nothing happens. I have checked the conectivity under media and the USB icon is greyed out. Any ideas?

Thanks in advance.

Insert the USB stick, then start the car it should then ingest the update - The usb stick should be formatted in FAT32 with nothing else on it, if its a new drive format it before use

Note. The stick must be formatted on a Windows PC (there are known issues with the way Apple's FAT32 formatting is implemented)

I take it the USB port works ?

Like flash22 said, USB stick must be formatted FAT32 and do I remember right that Toyota's headunits support only 16-32gb sticks?

32gb work but 16gb or lower is ideal for updates, with Audio on a stick any more than 16gb can take a bit to index as the touch2 hasn't got the processing power/ram
