REPAIR GUIDE
Repair request information for available CAST+, OTTOCAST, CAST Lite, and CAST All-in-One products. For TIGMA chargers, use the separate exchange and after-sales service guide.
Before requesting service
For usage or setup issues, first check the installation and troubleshooting guides. Confirm the product warranty period and purchase date, and back up necessary app/account data. When contacting us, provide your name, contact details, vehicle model/year, retailer, purchase date, symptoms, product version, and SIM carrier. Follow customer service instructions to check device identification information.
Request and product shipment
Contact customer service at 1688-9256 (weekdays 09:00–18:00, lunch break 12:00–13:00), Kakao Channel at https://pf.kakao.com/_xabsxbG, or Naver Cafe at cafe.naver.com/castmediabox. After registering by phone, our designated courier collects the product within 2–3 days, so you need not send it yourself. If you send it through another courier, you pay the shipping. Send to WAGLE MEDIA, Room 320, Building B, Hyundai Knowledge Industry Center, 70 Dusan-ro, Geumcheon-gu, Seoul. Remove the SIM and securely pack only the main unit (and cable if needed) in disposable packaging. Include a note with your name, contact details, address, vehicle model/year, retailer, symptoms, and enclosed items. Please use parcel delivery; we cannot readily accept liability for loss through regular mail, same-day courier, or registered mail.
Processing and return
Collected products are diagnosed through firmware updates and testing, then faulty parts are replaced or repaired. Failures during normal use within warranty are free; out-of-warranty issues, misuse, water damage, natural disasters, or unauthorized disassembly (including firmware) are chargeable. We provide a quote for parts + labor + 10% VAT and proceed after consent. If repair is difficult, we exchange the unit for a quality-tested refurbished product (counted as a repair). A repeat failure in the same part within 2 months of a paid repair is repaired free. Average turnaround is about 1 week including round-trip shipping; extended testing may cause delays. Return shipping is free within warranty; customers pay for out-of-warranty or paid repairs. Even for an out-of-warranty product, failures during normal use within 2 months of a refurbished replacement are repaired free.
