I purchased g2227 and install is ok. then i tried to add voice to my maps created an error. then my gps doesnt work. i contacted eonon they have been very helpful in trying to fix my problem, send me an upgrade file from their tech and I got it fixed. All quite smoothly. i can not say enough how happy i am with their customer support. sure sometimes they may be busy or emails. but my experience gives them a score of 10 out of 10 for communication, replying in good english offering great ideas solutions. so generally speaking I'm quite satisfied!
