THANK YOU - Bring back LOCATE VEHICLE!!!!!!!!!


THANK YOU!!!! I truly appreciate that you listened to our feedback about this function. Thank you for bringing back this to our app. I hope others appreciate your diligence in working to make the app great for us. It’s easy to complain about things and it spreads like crazy. I wanted to also REJOICE and say THANK YOU and hope that spreads just as rapidly. The following HAS been corrected and was my original post - Please get RID of set location!!!!!!!! It does nothing!!!!!!!!! Bring back LOCATE VEHICLE!!!!!! SET LOCATION has killed the app. Please bring back LOCATE VEHICLE as in find it where ever it is like other apps. This “update” does nothing.

We truly regret to hear of your frustrations, Kiwi-sunshine. Rest assured, we have documented our feedback within our systems. ~Shikara

Awesome app


The app is amazing. I pull out my Apple Watch and can start my car from anywhere. Now that the technology has changed (LTE Apple Watch and even WiFi mode on non cellular models) you guys just need to update the app to work without the phone and just the watch. Keep up the good work.

[Original post]
I traded my 09 CTS for a 13 ATS just so I could use this app and remote start from my phone. The only thing missing is Apple Watch support. Developers make this app work for Apple Watch please. I want to unlock and start my car without pulling out my phone.

What happened to send to in dash navigation?


I’ve had the basic plan and always was able to use send to in dash navigation now they say I need a subscription. It’s in black and white on onstar’s web page that send to in dash nav is supported under basic. What’s happening? Per onstar website is the following
“OnStar Help & Support > Basic Plan
Services Included
The OnStar Basic Plan includes the following services (services may vary based on vehicle make, model and equipment):

Select features of your vehicle's mobile app: Remotely start your vehicle (if factory installed), send a destination to your in-vehicle navigation screen, and lock or unlock your doors — all from your smartphone. Not just near your vehicle – but anywhere you have a wireless connection.”
We have lost the ability to send to in dash navigation- please fix this.

Developer Response

Hi, to clarify, your Basic Plan does include Remote Access, Advanced Diagnostics, AtYourService and Dealer Maintenance Notifications. However, navigation is an additional service that can be added to your Basic Plan. By pressing your blue OnStar button, you can speak to Advisor directly to learn more about this. ~Ashley
