How do I add a new vehicle and decode its VIN to auto-populate specifications?

Add vehicles to your garage and let Rennch automatically populate specifications using your VIN.

On iPhone/iPad

1. Open the Garage tab from the bottom navigation bar
2. Tap the “+” button in the upper-right corner (or tap “Add Vehicle” if your garage is empty)
3. Enter your VIN (17-character Vehicle Identification Number) in the VIN field
4. Tap “Decode VIN” — Rennch connects to the NHTSA database to retrieve:
   • Year, Make, and Model
   • Engine specifications (cylinders, displacement, horsepower)
   • Transmission type
   • Body style and drivetrain
   • Manufacturer-recommended maintenance intervals
5. Review and edit any decoded information as needed
6. Add a vehicle photo by tapping the photo area and selecting from your Photo Library or taking a new picture
7. Enter current mileage — this is essential for accurate maintenance tracking
8. Tap “Save” to add the vehicle to your garage

On Mac

1. Select the Garage section from the sidebar
2. Click “Add Vehicle” in the toolbar or empty garage area
3. Enter your VIN in the VIN field
4. Click “Decode VIN” to auto-populate specifications
5. Review the decoded information — all fields are editable if corrections are needed
6. Click the photo area to add a vehicle image from your Mac
7. Enter the current mileage
8. Click “Save” to complete

Tips

• VIN Location: Find your VIN on the driver’s side dashboard (visible through windshield), driver’s door jamb, or vehicle registration/insurance documents
• Edit Later: All vehicle information can be edited at any time by selecting the vehicle and tapping/clicking “Edit”
• Decoded specs aren’t perfect: VIN decoding provides a great starting point, but some details (like trim-specific options) may need manual adjustment
