GPS Repairs

Hi Everyone, Does anybody know anyone that does GPS Repairs?......I have a Garmin Navigator V that just stopped working....Still used it yesterday morning....last night it just wouldn't switch on....tried all the tricks to get it charged but no luck.....Auto Alpina said they cant fix it because it's out of warranty.....I have only done 7000km's with the unit in the last 3 years...It's basically still brand new and hardly used.
