When the HMI is pulled from the car it will not start! This is a special HMI-connector that allows you to drive the car while your HMI-radio/Nav is sent to us for GMAX conversion. When ordering our ICOS GMAX, we give you one for free. Order here if you need more than one.
When ordering make sure to leave following info about your GM car.
- VIN-number (all 17)
- model year,
We do not have access to GM’s VIN number system and need it in clear text.
