I know nothing about their quality. I normally buy a pair of two from my local guy when I throw out a pair. I am sure they are all made in China by now? They are tough ans do not wear out often even after many wash and dying cycles. I am not sure what the ads are on the sock, personally I don't care, nor do I care if my jersey match the color of my gloves.
I can't help you with the Garmin thing. I don't have any of the computer thing on my bike but I will ask around for you MIke.
