Navigation SD Card
No wonder we get bombarded with the GM Nav Card Emails. Not that I use the vehicles Nav system instead of Google maps, but ..... The other day in my other GM vehicle (Acadia), I tried to use the Navigation GM supplies, but I received an error SD Card missing, but it was put in and yes I did all of the normal fix/retries. Extensive search - requires visit to dealer to fix - could be many different reasons.
Reason for even trying to use was Google maps didn't work - short answer I had changed my google password on desktop and not copied to phone so if you are not logged into Google, you can not use maps. It took quite a while to figure out the reason as there was no obvious error message - loaded, put in info, routing just didn't work. Thanks Skynet.
Reason for post here is - Has anyone with a C8 had this problem if they ever used it on the C8 vs their phone? I do not recall it being a C8 issue, but it is rampant with many other Chevy vehicles.

My dealer is 2-4 weeks out on appointments, with multiple appointments required (Investigate, order SD card, install / no fix / order new reader, ...) I don't have months available to deal with it right now, so putting it off until summer.
Cost to dealer for new SD card is apx $450 under warranty - reimbursed
Not the $150/$99 we get in emails for RENEWALs.
That is why so many trips, ... Card is not transferrable to a different vehicle if it doesn't fix the problem.

With all the third party apps available (I use Waze) isn't the factory GPS/Nav irrelevant? Wouldn't bother me if the factory nav went the way of the dodo bird. It should be an onboard nav, updated through the normal update system, without the need for a special card.

Valid. But the need for a card is antiquated. You should be able to have factory nav without this 25 year old card technology.

As usual, threads deteriorate into off issues vs a discussion of the OPs question. It wasn't the merits of the C8's nav vs waze vs maps, it was if C8's were having the same problem and that was answered. The problem appears across ALL of GMC.
As to the merits merits of C8's nav, if you read the first post, my phone was inop re maps and for the first time I actually needed to use my Acadia's nav and discovered that it was inoperable. The same could have happened in the C8 if I had been driving it. My phone's maps were inoperable and if the C8's nav was inoperable I would have the same situation.

Thanks. I've done everything on every forum that everyone has mentioned plus standing on head while spinning a hulahoop on my left leg and juggling with the right one. Just kidding. Going to have to go to the dealership multiple times- they have a long series of steps to check because the parts are too expensive and they have to follow the GM protocol or they have to absorb the cost. However I do not have the time currently for this inconvenience.

I agree the in car GPS navigation will hopefully go over the air, but imagine the update files would be huge in size.

Waze and Google Maps for navigation are only as good as your access to cellular data reception. In remote areas and there are many, GPS navigation is the only way to go.

Your phone will work for doing GPS without a cell or data signal. The one thing you need is to make sure you have the maps downloaded. Phones have had this capability for the last 5 years or so. This article is focused on hunting but the tips in it work regardless. https://www.onxmaps.com/hunt/blog/do...k-without-data

Google always prompts me to download maps if I plan a route that takes me away from my home area.
