2. Applicable Models and Compatibility
The UA13-PLUS is a 10.1-inch Universal Double DIN Head Unit designed for broad compatibility. It can be installed in vehicles with a dashboard opening size of 178mm x 100mm (7.01" x 3.94") and an ISO power cord. For other dimensions, an additional installation kit may be required.
- Direct Installation: If your original car radio's mounting size is 178x100mm and it uses an ISO power cord, direct installation is possible.

- ISO Power Cable: Ensure your factory car radio's power cable connector is an ISO standard connector. If not, a separate adapter cable (not included) will be necessary.
