There seems to be so many GPS's covered by this forum, I find it hard to determine those dealing only with the Ique 3600. At age 73, I'll admit to not being the sharpest knife in the draw. But I'd still like to get my Ique 3600 up & running. I've read that down loads for the wrong unit can disable your unit. But the "Latest Downloads" don't list what GPS they are intended for. I joined this forum in hopes of going through the problems I have. I tried to PM Ann & the Cat, but seem to be blocked. Can you help?
