My wife bought me a helix 5 di gps for Christmas. I hooked it up in my house to put in some waypoints that I had on my phone. After putting in 20 waypoints I decided to take a break. Turned unit off. When I turned it back on none of my waypoints had been saved. All settings had went back to default. I was using the simulator to set waypoints. Tonight I tried again with same result. So first question is do I need to use simulator for this task. I also ran a self test and it showed that the gps isn't connected. I don't have a sd card in either. I think this is something small that I'm overlooking but not sure. Thanks for any help!!
