Garmin have, over the years, produced some excellent GPS automotive devices and they still do.
I don’t think they will quickly lose their ability to be really good at knowing how GPS functions ’work’ but their days (like that of telexes, faxes, CD’s and now cameras, too) of producing and offering physical GPS devices are probably numbered. In short, they have lost:
A. To the smart phone.
B. To bods (and there are lots of them on this forum) who do not want to create their own routes at all. All they want / need is a phone (or an implant if one were available) to tell them how to go from A to B on either main roads or twisty roads. They do not need a bespoke GPS device at all. Yes, they’ll sometimes moan that the vibrations of the bike buggers up their phone’s camera and / or it doesn’t always work when the screen is wet or it shuts down if it gets too hot in the sun, but those are faults that can be fixed by the phone’s makers. That the phone will always link seamlessly with their TFT screens / displays in the car and on their motorbike and will share perfect routes with their mates, so nobody needs to get lost ever again *, is just a bonus.
Garmin’s role will maybe change to being a consultancy, in the same way that F1 teams offer engineering consultancy to other manufacturers. Or, like others before them, they’ll go bust. Panasonic fax machine, anyone? Or, as EVskij suggests, they will stop producing what are now overblown infotainment systems ** (that won’t beat a phone anyway) and instead concentrate on solidly built, very reliable GPS devices, easy to use and capable of easily accepting bespoke routes.
* They will, of course.
** As demanded by loads of bikermates, who want to be connected and entertained for every moment they are out on their motorcycle.
