Decided to Take my Garmin to the City since its the most difficult place to navigate specifically San Francisco. I had multiple stop to make and I lost Satellite signal every place i was traveling. Given most of the places were surrounded by High rise buildings but I would have to pull over and wait for signal or just drive till signal came back I even tried rebooting the device but same problem. I wanted to toss the Garmin out of the car. I could see being in a parking garage or underground causing no signal but It seemed like the Garmin failed when i needed it the most. Anyone know what to do when this happens.
