Due to the high volume of shipments we get on a daily basis, there is a specific process that needs to be followed to insure that no radios get lost in the shuffle and create a further delay in completing your order:

After placing your order you will be directed to a download page with your order confirmation. You will want to make sure and print off a copy of this order confirmation to place inside the box with your radio being sent in. The download page will have instructions on how to properly box, protect and where to ship your radio in for the work. Depending on our current workload, the email with the ship to address may take some time, so feel free to use the message app below to request the address if you want to get your radio shipped out quickly. We recommend shipping  your shipment with either UPS or FedEx, and make sure to place insurance on the package, so that you are covered if the shipment goes missing or gets damaged along the way. MVI is not responsible for any loss or damage caused by the shipping company you choose to use when sending your radio into us.

At this point, MVI will begin building your Buick LaCrosse IntelliLink Wire Harness and place your order on the “radio send in” waiting list. Once the radio arrives, we will perform the required work to the radio (1-2 business days), box it back up with the new harness kit and ship it back out to you complete using the insured shipping label we will provide. You will then get a final email showing the order has been completed and we will provide you the tracking information being used to track the package back to you with.
