Just attempted to download the most recent Beta up grade from the Garmin site. Everything going swimmingly, GPSV, having erased previous knowledge, is happily installing latest top notch version 2.12 or somesuch, and then with just 1min 29 secs to go, stops. "Missing software" it states on its little grey screen...retry, as per instructions on download site...same result at the same stage. Go and make cup of tea, come back, GPSV is no longer showing any message or indeed any sign of life, its screen is blank. No amount of fiddling, pushing start button, changing batteries, trying mains cord has any effect. GPSV is toast. Only had it 9months and I just hope I can find the receipt....
