My tuner (wheel) does not work well. Direct punch in of numbers is fine. I am concerned that it might be an accretion of dust and other gunk. It is old! Can I use a computer spray type cleaner to clean it? Is is openable and cleanable like other electronics?... 论坛: diplofix.com - 发件人: ontheroad - 日期: 2008-09-30 18:38:51
