Received unit yesterday. My son and I tried for several hours to figure out why it keeps looking for a satellite signal and never advances further. We tried multiple regions. Unfortunately technical support of Garmin is only open on business days 8-8. No benefit from FAQS site at Garmin web site. After several frustrating hours, I have arranged for a refund. Sorry to burst any bubbles, but this one's a lemon! Only saving grace is that Amazon makes it fairly painless to return. Will look into another company instead.
