For cars outside of USA, in some case if device is recognized and work properly but only for few seconds you will need to visit your
dealer and apply MOST Security OFF patch. This patch can be removed by the authorized dealer only. This patch will allow third party
integration devices to work properly with your factory stereo. Currently there is no workaround been found besides visiting the dealer.
For cars within USA, there are some rare cases, if the car was imported to the US, it might have MOST Security ON. No any Volvo dealer within US
has the ability to turn it off. In that case you can return the kit back to us within 30 days for the refund.
