Last week I had a remote-starter put in my car. Unfortunately, the mechanic found it would only work when SyncUP Drive is physically disconnected. Each time we put it back in, the remote-starter would fail to turn the car on. Remove the SyncUP, and things return to working order.
The dealership rechecked the remote-starter install, and indicated it’s a completely standard install and not an issue they have seen with any other similar OBD-tracking device.
Has anyone experienced this before? Any ideas for how to fix or troubleshoot?
I have tried in-store, chat, and phone support for Tmobile. Mostly, I receive head scratching responses, and no concrete recommendations or contacts w/in Tmobile to try for deeper help.
