Just bought a Bryton Rider 50 GPS but having real trouble with the mapping functions.
Before I installed the HD Maps UK & Ireland CD onto the internal memory card I could see place names and major roads around London when I zoomed out. After installation, now I can see road names zoomed in but when I zoom out more than two clicks I just get blank landscapes with no place or city names.
Really frustrating as have spent hours farting around to no avail and should be out on my bike. Any ideas?
