Don't forget to...

Had a horrible journey the other day. I set off at the normal time, which gave me a fair bit of leeway to get there in time. As I hit the motorway, the TomTom got the traffic info, and told me there was 37 mins delay. And that my time to arrival was 11.37. Yike - I'm supposed to be there at 11. I don't recall this being that different. Hopefully it will go down as people get to work. But it didn't. I got the the tail of a 32 minute delay, and as I pulled up to a dead stop, the delay changed to 48 minutes. And then the satnav said "there is a faster route, would you like to take it?" Too right, and I moved across the lanes to leave at the exit just a few hundred yards away. I drove along A roads and occasionally saw the motorway, still crawling.

As I got back onto the motorway, I checked where I was on the journey. About two hours to arrival, 60-odd miles to go. No, hang on, how can that be? What time is the satnav showing? Hmm. Oh poop.

Yes. When the clocks change, don't forget to change your satnav clock too. I got there with 15 mins to spare, quite comfortable, despite the delays.

I'm told in another place that most Garmin satnavs "know" when the daylight saving changes, and do it automatically. I can't see mention in the spec pages I've looked at that it is in the core of GPS, so it must be in software, which means it may be vulnerable to error when these things change.

I set mine the other day and synchronised it with the satelite time, but noticed that satelite uses UTC (GMT) so obviously doesn't change to BST anyway.

My 740 and that of a collegue at work didn't automatically go back an hour. Even though mine had 20 minutes of good signal to do it. I had to change the hour myself and then hit Save. If i didn't hit Save the sync button just put the hour forward again.
It appears it'll sync the minutes but not the hours which had to be set manually. This was the same when it went forward earlier this year.

Yup, the only ones to get it completely right are the 1000/1005.

Sync will always take it to the "last remembered hour". I had this when I went to the USA. I arrived, and had to manually change the hour. Once saved, it knows that this is what you want to sync to. Good to know that they have it sorted in the future versions.
