Riding an ultra-race recently and ran into an issue with the 1040 zoom function. Upon entering a town I would zoom in so I could see greater turn and street detail; however, once I made a turn at the next point, the device would zoom back out to the default zoom level. I went into Settings and adjusted what was available but the lack of control and having to continually zoom back in manually was frustrating. Is there something I'm missing? Any help is appreciated.
