Update conundrum

[Racer]

Morning all,

Just got the reminder to update my Garmin 660 LM, changed the SD card to one of sufficient size following advice on here, it now appears to be stuck on 58 mins and "building"
Its been like this for an hour, in fact since i plugged it in, and no change - also the message "safe to walk away and do not disconnect unit"
Am i being impatient or should i turn it off and on again ?
Im using a MAC book pro if that has any bearing on the matter

Cheers

Rich

A watched kettle never boils.

Be patient for a bit longer.

It's a BIG file which, depending on your download speed and the assorted processing power of your computer and the device itself, may well take some time.

Thanks, will do, it just seems to be doing nothing at all, just the blue chevron download bar, and two hours remaining - deep joy
I have selected to install on the laptop and the device, maybe thats the problem ?

Cheers

Well, after much swearing/waiting and even more swearing, I turned off my laptop, restarted it, cleared the cache memory, restarted my sat nav and bingo - success, I did piggy back of my friends super fast broadband as well - result. New european maps downloaded on laptop and satnav

Result! My broadband speed is less than 0.5mbps, so I get a nervous twitch every time there's a map (or any other) update notification from Garmin. Last update I had (CN 2015.4) took over 36 hours to download and update (to MAC and Device).

Finally purchased lifetime map for my Zumo 550 yesterday which was running on a NT2008 euro map.
I have a 8GB SD which took the new 'supp' map (3.96gb when .img) and I left the old one on just in case. Loaded the upgrade to basecamp first and then used mapinstall to load it to the SD card sat in the Zumo.

Loading times were large as Racer found out - I have a wire internet so at about 4mb/sec it took a few hours and then I used the Zumo to move the upgraded and unpacked file to the SD card - that took 2 hours (USB 1) - in hindsight I could have popped the SD card into the Macair which would have been a faster transfer (USB 2). All loaded fine and then deselected the old map on the Zumo to finish the exercise. Now going through my routes cleaning and updating in basecamp, just like to say thanks to Wapping for the research on basecamp
