"Really nice, works perfect, fast, easy setup"4.5 starson by fmklem
Pros: fast ,easy to AND hear, a leap forward from paper maps
Cons: Company WEB site is next to useless & they don't answer emails.
Summary: When I first got F20 I thought it was defective because it wouldn't turn on. I discovered that you need to hold the start button pressed until F20 turns on. (Instruction book doesn't mention it) Once done I was impressed with how fast it gets satellites and ease of use. I found the voice to be more than loud enough in my large car. All in all its a huge step forward from paper maps.
Before I retired I used a laptop GPS during work and this GPS is much better / easier to use because of the 3D effect. Never again will their be tense moments between husband and wife in our travels to unfamilar places.
