Stop recommending the Vlinker update

The third party app is trash and it irresponsible for the developer of this app to “require it”

Response from developer

The update isn't required — the app works fully without it. It only affects door lock/unlock, remote climate and remote start, which can't work on the firmware the vLinker MS shipped with; Vgate's updater is the only way to reflash it. To stop the message now, tap "OK" on the dialog rather than tapping outside it — it only remembers your choice when you use a button, which is a bug I'm fixing.

Must Have for Volt/Bolt Owners

This app provides much more in-depth and historical data than standard OBD scanners for Volt/Bolt owners, which has historically been difficult due to their weird connection profiles. It also has the ability to control low-level features, such as the battery heater pump, and high-level features, like turning on the rear camera without being in reverse, among lots more which is awesome. Totally replaces the need for the now less than supported MyVoltControl and MyGreenVoltConnect apps while looking much more modern. Developer is super responsive and active as well, worth the purchase to access all the features for sure!

no trial or free features

everything is locked behind a paywall and nothing useful is made available for free, making it impossible to gauge how useful/effective the paid version of the app could be.

Response from developer

The app offers a lot for free: Expert data view, DTC reading, decoding, and clearing. Live monitoring with plenty of free parameters. Scan history with charts, import and export.
