Any recommendations for getting a Dittel FSG 71M serviced?

I changed the battery in mine and also replaced the LCD screen about 12 years ago. While the radio is very compact I think components were large enough that you could work on it without a microscope. It stayed in the glider when I sold it in 2009. The LCD screen was very easily damaged by heat and pressure (clean it very gently). Another minor flaw was that the radio would go crazy if I forgot to turn my cellphone off while flying.
