Panasonic Radio Code

Panasonic is a major Japanese OEM automotive electronics supplier, manufacturing factory-fit head units primarily for Toyota and Citroën/Peugeot (PSA group) vehicles. If your radio is displaying CODE or LOCKED after a battery change and the unit is factory-fitted to a Toyota, Citroën, or Peugeot, there is a strong chance it is Panasonic-built. This guide covers the serial number format, location, and how to enter the unlock code.

Which Vehicles Use Panasonic OEM Radios?

• Toyota — Yaris I/II/III (P1/P9/P13), Aygo I/II, Auris II (E180), Corolla IX (E120), C-HR — using Panasonic/Pioneer and Fujitsu Ten/Pioneer OEM platforms including Toyota Touch and Toyota Touch & Go units
• Peugeot — 107 I/II, 108 I — the Peugeot CQ-JF10 (Toyota OEM) unit is Panasonic/Pioneer — shared with the Aygo/C1 city car platform
• Citroën — C1 I/II/facelift — same CQ-JF10 / Panasonic-Pioneer platform as the Peugeot 107/108 and Toyota Aygo

The CQ-JF10 — A Shared Platform

The CQ-JF10 (OEM part number) is a Panasonic-built head unit shared across the Toyota Aygo, Peugeot 107/108, and Citroën C1 city-car trio — all manufactured on the same platform at the Kolin factory in the Czech Republic from 2005. The radio is physically identical across all three brands; only the logo on the fascia differs. It uses a standard serial number on the casing label.

Serial Number Format

Panasonic OEM serials are plain alphanumeric strings, typically eight to twelve characters, on a white barcode sticker. There is no standardised prefix across platforms:

• Toyota / Aygo / Yaris: Serial printed below the barcode on the unit casing label
• Peugeot 107 / 108 / Citroën C1 (CQ-JF10): Serial on the C7 barcode label or a secondary sticker on the unit
• Toyota Touch / Touch & Go touchscreen: Serial accessible via the head unit's own system information menu

How to Find the Serial Number

1. Toyota Touch / Touch & Go — on-screen: Navigate to Settings → System Information on the touchscreen. The serial number is displayed there.
2. CQ-JF10 (Aygo/107/C1) — on-screen shortcut: With the ignition on and the radio powered, press and hold preset buttons 1 and 4 simultaneously for two seconds to display the serial on screen.
3. Physical label: Use a plastic pry tool to remove the unit. On the Yaris and Auris the head unit slides out after removing the centre console trim. The serial sticker is on the top of the unit casing.

How to Enter the Code

• CQ-JF10 / Toyota Yaris / Aygo: With the radio displaying the code prompt, use preset buttons 1–4 to cycle each digit (each press increments by one). Press the seek/scan button or hold the last preset to confirm.
• Toyota Touch touchscreen: A four-digit PIN entry pad appears on the touchscreen after startup. Tap each digit and press OK.
• Peugeot 107 / 108: Preset buttons 1–4 for digits; button 5 or 6 to confirm (consistent with PSA RD4 family input conventions).

Vehicle	Radio System	OEM Supplier	Entry Method
Toyota Aygo I/II	CQ-JF10 (OEM)	Panasonic / Pioneer	Presets 1–4, seek to confirm
Peugeot 107 / 108	CQ-JF10 (Toyota OEM)	Panasonic / Pioneer	Presets 1–4, confirm 6
Citroën C1 I/II	CQ-JF10 (OEM)	Panasonic / Pioneer	Presets 1–4, confirm 6
Toyota Yaris I/II/III	OEM CD/radio	Panasonic / Fujitsu Ten	Presets 1–4, hold last
Toyota Auris II / Corolla	Toyota Touch	Panasonic / Pioneer	Touchscreen PIN pad

Troubleshooting

• LOCKED after wrong entry: Panasonic Toyota units typically lock for 30 minutes after incorrect code attempts. Switch the ignition off for the full period before retrying.
• Peugeot 107 shows code entry prompt but code not accepted: Double-check the serial — the CQ-JF10 has two stickers, one for the part number and one for the serial. The serial is the shorter alphanumeric barcode, not the long part description.
• Toyota Touch & Go shows no code prompt after battery change: Later Toyota Touch & Go II units handle reactivation via the vehicle network and may not require a manual code. If the system boots normally, no code is needed.

Frequently Asked Questions

Why does my Toyota Yaris radio show CODE after changing the battery?

Toyota OEM radios (built by Panasonic, Fujitsu Ten, or Pioneer) use a theft-protection code that activates on any power interruption. It is a standard anti-theft feature, not a fault. Entering the correct code restores full functionality.

Is the Peugeot 107 radio the same as the Toyota Aygo radio?

Yes, physically. The CQ-JF10 is the same hardware in both vehicles — only the logo badge differs. The serial number and code lookup work identically. You can select either Peugeot or Toyota on the brands page, depending on which make you have.

Can I get the Toyota radio code from the dealer?

Toyota dealers can retrieve the code from the vehicle's VIN history, but this service may have a charge and requires an appointment. A serial-based lookup from the unit itself is faster in most cases.

Where is the serial on a Toyota Auris II head unit?

The Auris II uses the Toyota Touch touchscreen system. The serial number is available via Settings → System Information on the touchscreen without removing the unit. If that option is not present, the unit can be removed by unclipping the centre console surround and sliding out the DIN cage.

Does the Citroën C1 use the same radio code as the Peugeot 108?

Yes. Both cars share the PSA-Toyota city-car platform and use the identical CQ-JF10 Panasonic unit. The serial and code lookup is the same regardless of badge. Visit radiocodelookup.com/brands and choose your brand.
