Programming Services and Processes:
Please Note:  In order for the new radio to function in your vehicle it will need to be divorced from the donor vehicle and set back up specific to your vehicle. MVI offers this custom programming service for $225 and this does include the ground return insured shipping of the radio back to you. 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. 

The process is as follows: After placing your order above you will immediately be sent an email (to the email address provided at checkout) with your order confirmation and placed into our On-Hold order cue while we finalize previous customer orders. This On-Hold process typically takes 2-3 business days, depending on order volume. 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. Once we have placed you into our processing cue you will receive another email (to the email address provided at checkout), that will contain instructions on how to properly box, protect and where to ship your radio in for the work. We recommend shipping and insuring your shipment with either UPS or FedEx 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.

It is at this point that MVI will begin building your 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.
