Garmin Drivesmart 76

Management has bought me the above Garmin to replace my Nuvi 57. In most respects it looks mostly the same but more up to date and a bigger screen. It says it has Live Traffic. I assume this means it updates traffic problems en route. 
Trying to read through the on line instruction manual it mentions a sim card and there is a slot in the back for it. Am I right in thinking it needs a sim card for the live traffic. If so none technical instructions may be required please.

I have a garmin but different model, It does give live traffic updates and also adds time to journey if delays encountered. For interest the power lead from 12v skt is the aerial for this function. Mine also has slot in back but for memory card, this is to increase available memory for route planning and   Updates etc.Probably enough on as fitted memory without large numbers of planned routes stored but I put a memory card in and just forgot about it and have not had issue in last 3 years of use and all updates been added as and when available.

Same as Kdc …

Thanks Kdc that’s why the forum shines out for me. I was going through my spare leads from my older Garmin and noticed they were different plugs and a bit thinner. The way the old power cable was routed it was hidden under the edge of the dash but I think the new one would benefit from being routed along the top of the dash if it’s the aerial.
I get the idea of the SIM card for extra storage and I might look into it.

Whilst I was replying to Kdc I didn’t see the reply from Mike and am now totally confused:scratch head:.
I am one of the rare none tech people that dosnt have a smart phone. I have a Hauwei thing for WIFI on our trips for my i pad so does that mean I can’t use the Live Traffic. Has it got to the point were any one that’s not tech savvy is being left behind unless you have an I phone. 

It does not not need to be connected to a smart phone for live  traffic updates although the charging lead that came with it has to be used , it will only update on live traffic if you have a route planned and will sometimes offer a detour, I have my lead under the dash mainly as I have hard wired it to the fuse box.

The app for the smart phone or iPad is useful for finding campsites ,attractions using search for sites to send the details straight to the sat nav, it’s called Garmin smart link

Thanks for all youre input folks. I am getting the gist of this now. I think my next move will be to try and see what happens on route. My technical skills are better proven with a spanner and a hammer.

I have been out to the motorhome and had a play to see if I need to alter the mounting and power socket. Whist I was in there as the web site said it needed linking to a satalite to correct its position and adjust the clock.
The bigger screen and faster search times are a vast improvement. It fits on the same mounting and the lead is plenty long enough.
 It found the  local nature reserve we visit without having to put the road name in or nearest  town. 
The idea of having the i pad on whist we are on the move will need the Huawei on as well all needing powering up . As you sugested Mike I will check the model number.
 I have seen an A Class with lots of devices on the top of the dash and thought it looked very messy. There were a  lot wires trailing about to keep them powered up. They must have had more solar and battery power than I have.

We had a trip out today using the Garmin. The combination of the larger screen and more up to date features made a vast difference. I found a couple of things were not activated and the traffic update didn’t prove itself so far.
