Okay, so today I missed my stop on the bus because my vision is getting so bad I can't make out the shapes of buildings anymore. Now, I've heard of a program called wayfinder for mobile phones. Would this help me... Like would it bleep ... or buzz ... or vibrate ... or speak to inform me that I am approaching my destination? How does it work, any URL where I can read up on it. And cost? And phones that it will work with? Peter
