Does what I need it to

Tark Jones

Overall it's a solid app. It does the basic stuff well. I primarily use it for remote start which is great since its essentially unlimited range. I've also been able to unlock my wife's truck for her when she accidentally locked her keys in it. It works well the majority of the time, but can sometimes have an issue with a signal getting through if you're in a parking garage - which I assume is a function of the service provider not the app itself. Overall its a very convenient tool to have.
One thing to watch for -- if you have two GMC vehicles on the app, double check to make sure you have the correct vehicle selected. I have started our other vehicle by mistake when it's sitting in the garage.
To the developer: it would be nice if the banner image reflected the vehicle currently selected, instead of a generic GMC line up. That would provide an easy identifier for those of us with multiple GMC vehicles to quickly confirm which vehicle is selected. Even allowing the user to upload an image would be a useful option.

***UPDATED (see my original review below)***
After my original review, several emails, etc., the app finally began working correctly. No official determination on the actual problem, but I’m happy that it actually works. It IS a GREAT app and I’m happy to be able to leave a positive review. Both OnStar and GMC are awesome companies that have excellent customer service.
********ORIGINAL REVIEW********
I LOVED this app, until it updated and took away all the features I use... Those features may still be there, BUT since the app refuses to identify my OnStar account (which I have confirmed is current with OnStar), I can no longer use them. So, I cannot remote lock/unlock or start my car, check diagnostics, send addresses to my navigation, etc. All these functions are the purpose of this app for me, personally. I am very disappointed.

GM Takes Away Features to Force Onstar Purchase

Winter Soldier 71

So after two years of having a General Motors vehicle, a GMC Yukon Denali and having basic OnStar which I feel should have basic features I have had my send to navigation option taken away from the app after two years with no notice and no consideration for the fact that we own multiple General Motors vehicles.

you took away navigation from the consumer in order to force a sale of higher priced OnStar services which I feel only makes your product now look less desirable and I hope that everyone reading this will consider not purchasing a General Motors vehicle based on the heavy-handed approach that you have taken and taking away the liberties of a simple send to navigation.

I noticed that as developer you were leaving remarks back to bad reviews please don't bother leaving a standard copy and paste remark telling us about how awesome General Motors is when all you do is take away features and force people to pay for things they didn't have to pay for before.

I moved from Jaguar and Land Rover to GMC and Cadillac, I have owned BMW and Mercedes very happily. As quickly as I divorced them I will divorce you General Motors and I will go back to your German adversaries. This is an absolute shame in business ethics that you would resort to nickel and diming a simple navigation feature to try and push your ill prepared and very non-feature-rich OnStar services.
