Frequently Asked Questions

How do I fix activation transmission bugs?

Most authentication loop issues require a direct server refresh command. You can reach our configuration team live to push an over-the-air execution sequence immediately.

Can I transfer my existing service plan to a new car?

Yes. Transferring setups require capturing the old radio's account details alongside the new hardware's 8-character terminal code. Contact our voice support platform to execute accurate data mapping.
