🔍 The Compatibility Issue
W702BS, W502BS, and W602BS users with BMW motorcycle keyless navigation mount (Cradle) may experience the following symptoms:
- ❌ Signal disconnections: Intermittent connection drops during rides, causing navigation and audio interruptions
- ❌ TFT-NAV icon disappearance: The TFT-NAV icon on BMW dashboard disappears and reconnects frequently
- ❌ Wonder Wheel control issues: BMW's Wonder Wheel control becomes unresponsive or unstable
💡 Good News: These issues are related to the same root cause and can be resolved with a single firmware update to MCU v1.18 and the latest decoding software.
⚠️ Before You Start: Verify your device model is W702BS, W502BS, or W602BS and check your BMW Cradle version. See detailed compatibility check in the Important Notes section below.
✅ Complete Solution: Update MCU & Decoding Software
To resolve all compatibility issues, you need to update both:

🔧 Step 2: Update MCU to v1.18
Choose one of the following update methods:
▼ Option A: OTA Update (Recommended - Easiest Method)

💡 Tip: OTA updates are the safest and most convenient method. Make sure your device has at least 50% battery or is connected to power during the update.
▼ Option B: Manual TF Card Update
Best for: Users who cannot access MCU OTA settings or OTA update fails
- Contact Carpuride support at service@carpuride.com to request the MCU v1.18 update file (specify your device model: W702BS, W502BS, or W602BS)
- Download the update file to your computer
- Format a TF card (microSD card) to FAT32 format
- Copy the update file to the root directory of the TF card

📋 Important Notes & Best Practices
⚠️ Verify Device and Cradle Compatibility
Device Model Check:
- This solution is ONLY for W702BS, W502BS, and W602BS
- NOT for W702B, W702B Pro, or other BMW series products with "B" in the name
