This is a special service for replacing your own display audio system. We will determine whether installation is possible and what work will be required after examining your vehicle's structure, the condition of your existing system, and the specifications of the product you bring with you. For products brought with you, installation requirements vary significantly depending on the vehicle model, year, and factory equipment configuration. Therefore, we must inspect your vehicle and the product you bring with you in advance. Under no circumstances can we determine the installation price without these inspections. If, after inspection, we determine that necessary parts are missing, additional work or modifications are required, or installation is deemed difficult due to safety or durability considerations, we may change the work, incur additional fees, or decline the installation altogether. If you wish to purchase new equipment or install sound deadening, we recommend selecting one of our installation plans instead of the "bring-in" plan to receive the best possible service and price. This service is exclusively for customers who only wish to have their own equipment replaced.
