Built-in radar detectors are physically and structurally connected to the car and their installation/disassembly needs to be done by a specialist. We recommend transferring built-in systems between vehicles only in case of sale or exchange of the car. Another option for using one product in multiple vehicles is to purchase a portable radar detector and a kit for the second vehicle a kit for the second vehicle that includes a power cable / fixed-mount cable and a windshield mount.
