Summary: If I could give it no stars, I would. I own a Nuvi 660 that I really like. I have had no problems with it at all. Last Christmas I bought a Nuvi 1490, thinking I would pass the 660 on to another family member. It froze up on me the first day I used it and it wouldn't sync to my phone. I returned it and went back to the 660. In August I started looking again for a replacement for the 660 and I selected the 1690. I got it synced to my iPhone and made a test call.
Summary: I've had this unit for a week. While driving the NE corridor approaching NYC, I noticed some inaccurate info: the screen will say to stay in the right lane to continue on I-95N, while the voice prompts will say to stay in the left lane. This is horribly confusing when you do not know the area (I did not) and are relying on the GPS unit for directions. This happened multiple times - I had to eventually just turn the unit off.
Summary: I had a difficult time getting the GPS to work initially. I called Garmin, and the tech eventually determined that it was used previously, so the normal new system setup would not work. He was able to get me authorized to download the latest maps though, and assured me that the warranty was still good, so I thought all was well.
Summary: I decided to purchase the Nuvi 1690 before a big family road trip to Death Valley from Washington state. I was upgrading from a TomTom 130, and I wanted to have a more modern GPS with the Google search. Let's just say that I should have stuck with the TomTom. The first problems were encountered a few hours into our trip in Portland, OR. I needed to stop at a store and I entered the point of interest into the GPS ahead of time.
Summary: We purchased in mid December and during a recent trip the detailed map information stopped being displayed. In addition, we can no longer get directions to an address since the map info is gone. When you go to the info screen and look up what detailed map is loaded, nothing is displayed. Garmin support has not responded after waiting for 2 days.
Summary: This is just a typical Garmin unit, I like Garmin better than most of the other companies primarily for how they handle points of interest. I was disappointed the Google option is a separate search not integrated into the primary search but the Google search was useful and I could have seen using this as the default POI search tool, if I was going to keep the unit.
If you want to buy an AUTO Switch Off Sat Nav, go ahead and buy this one!

Summary: I HAD OWNED 2 GARMIN 1690 and RETURNED THEM BOTH. PLEASE READ IF YOU'RE CONSIDER BUYING THIS MODEL! NO HARM READING AND IF YOU CHOOSE TO GO AHEAD TO BUY THIS MODEL, YOU KNOW WHAT YOU MIGHT BE EXPECTING. IF I COULD GIVE NO STAR, I WILL! I've bought this Garmin 1690 in Xmas 2010, slowly noticing this Garmin loves to auto switch itself off in the middle of the navigation.
AVOID - This Garmin is much worse than previous generations

Summary: I upgraded to the 1690 model from the 660FM in October 2010, so at the time of writing, I have now been using the unit for about 6 months, which I think has given me a fair time to assess its performance on a variety of different trips. I'm technically minded and I have therefore ensured that the 1690 has been using the latest software version and the most up-to-date maps to try to ensure its performance is as good as possible. How would I summarise this unit?
