Padremo Posted October 21, 2019 Share Posted October 21, 2019 Hi all. Have just bought a 2017 Focus titanium x (moved from a 2001 Focus Ghia - I'm not 'into' cars so like to keep the same car for as long as possible) So I've updated the Sync 3 software to latest version and now need to do the maps, but am wondering how much the battery will drain if I install the Sync 3 maps (over 20gb) with the car engine not running? Ford say to do it on a long Journey, but when dealerships do the update for you I presume they don't go and drive your car for a couple of hours while it's installing (do they connect an external power source to the car?) Is it OK to do it with the engine not running, running but the car is stationary or is it best to go on a drive while updating? Thanks!

SgtAWilson Posted October 21, 2019 Share Posted October 21, 2019 If you ask for your dealership to do it, they will charge you for it. Its a while back when I updated my maps, and I think it took 40mins for the first part and then another 20, so I did it on a long journey. I suppose if you have a secure driveway then you could do it with the engine running. But as Ford specify, the engine does need to be running.

Comares2001 Posted October 21, 2019 Share Posted October 21, 2019 Can take up to 90mins to upload data in which time Sync3/Radio will shut down anyway without engine running that's why Ford say take it for a drive. You can stop car during update and it will pick up where it left off on restart. Dealer wont normally do it for you as they say its customers responsibility to update maps.

alexp999 Posted October 21, 2019 Share Posted October 21, 2019 I normally run USB updates with engine running and stationary unless I'm already planning on going somewhere. I think they just recommend not to stay stationary over dry leaves (hot exhaust/cat) Quote Link to comment Share on other sites More sharing options...
Jonro2009 Posted October 21, 2019 Share Posted October 21, 2019 I updated mine on the driveway with the engine running, I took the opportunity to do a forced regen and gave the car a good wash at the same time. Quote Link to comment Share on other sites More sharing options...
Padremo Posted October 21, 2019 Author Share Posted October 21, 2019 OK thanks all. The driveway is secure and leaving it running while I wash it is a top idea! Thanks 🙂 Quote Link to comment Share on other sites More sharing options...
gillyallan Posted October 21, 2019 Share Posted October 21, 2019 My wife loves it when we get a map update as we go a little run usually out to Clyde valley garden centres. Quote Link to comment Share on other sites More sharing options...
