I like to listen to music, but I'd like to be able to turn it down or completely off when needed. I have a slider that controls the volume, but I struggle with my glove to find the slider. Also, if I keep the IPOD in my jacket to protect it from rain then I cannot hit any control button to turn it on or off. Some people mount the music devices on their bikes, but how are they protected from the rain? I get so irritated when the IPOD charges runs out on a long day of riding. Is there a way on the bike that I can charge the IPOD? Any advice would be appreciated. Thanks.
