Panasonic’s official Subaru information lists CN-LR820DFC under the 2016-model Subaru navigation systems.

Panasonic’s official map documentation also explicitly lists CN-LR820DFC as a supported navigation model for applicable map SDHC memory cards.

The CN-LR820DFC is a Subaru genuine navigation model from the 2016 model group. Because Subaru installed different navigation systems across different vehicles and grades, the navigation model number is more important than the vehicle name alone.

Customers searching for this navigation may come from Subaru models such as:

• Subaru Legacy
• Subaru Legacy B4
• Subaru Legacy Outback
• Subaru Forester
• Subaru XV
• Subaru Impreza
• Subaru WRX
• Subaru WRX STI
• Subaru Levorg

Important compatibility warning: These vehicle names should be treated as related Subaru search terms unless the vehicle’s actual navigation unit has been confirmed as CN-LR820DFC. A Subaru vehicle does not automatically use CN-LR820DFC.

For the safest identification, check the model number printed on the navigation unit, the original map card, vehicle documentation or the navigation settings screen.

A major search intent for Japanese navigation customers is Panasonic Strada Map SD Error Fix. Customers may not know the navigation model when they first experience a map-card problem and may search by their Subaru vehicle, Panasonic navigation brand or the message displayed on the screen.

Common problems customers may search for include:

• CN-LR820DFC map not loading
• CN-LR820DFC map SD card missing
• CN-LR820DFC SD card not recognized
• CN-LR820DFC map card error
• CN-LR820DFC navigation map error
• CN-LR820DFC map data cannot be read
• CN-LR820DFC navigation SD card replacement
• Panasonic Strada map SD error
• Subaru Panasonic navigation SD card error
• Japanese Subaru navigation map card missing
• Original navigation map SD card damaged
• Navigation system unable to read map media

A replacement map SD card may be appropriate when the original map media is missing, damaged or otherwise unreadable. However, the navigation unit itself can also have hardware, software, power or other faults, so an SD-card problem should not automatically be assumed to be a card failure.

Customers with Japanese-market navigation systems may search using Japanese error messages displayed on the navigation screen. Related map-card wording can include:

• 地図SDカードを挿入してください — Please insert the map SD card.
• 地図カードを挿入してください。 — Please insert the map card.
• 地図カードがありません。 — Map card is missing / Map card not found.
• SDカードを確認してください。 — Please check the SD card.
• ファイルが見つかりません。SDカードをご確認ください。 — File not found. Please check the SD card.
• 地図データを読み込めません。 — Map data cannot be read.
• 地図データがありません。 — Map data is missing / unavailable.

The exact error wording can vary according to the navigation software, map-data version and system condition. These phrases are included as related troubleshooting and search terms and should not be interpreted as a guarantee that every CN-LR820DFC unit will display every message.

Panasonic’s official documentation confirms that CN-LR820DFC is supported by applicable Panasonic Strada map SDHC memory cards. The official 2022 map documentation explicitly includes CN-LR820DFC, and the 2023 map documentation also lists CN-LR820DFC among the supported models.

Panasonic’s official Subaru navigation page explains that customers using the 2016-model CN-LR820DFC can use Panasonic’s map-update application for navigation registration and map-data updating.

This is useful for customers searching for:

• CN-LR820DFC map update
• CN-LR820DFC latest map
• CN-LR820DFC map SD card
• CN-LR820DFC map SDHC card
• Subaru CN-LR820DFC map update
• Panasonic Strada CN-LR820DFC map

Map editions change over time, so customers requiring a particular map year should confirm the exact map version before ordering.

Step 1 — Confirm CN-LR820DFC

Before ordering, confirm that your factory navigation unit is specifically identified as CN-LR820DFC.

Step 2 — Check the Existing Map Card

If you still have the original navigation map SDHC card, check its label and condition. Do not format, erase or modify the original card unnecessarily.

Step 3 — Confirm the Map Version

Different Panasonic map editions exist. Confirm the map-data year/version supplied with the replacement product.

Step 4 — Insert the Map SDHC Card Correctly

Panasonic’s documentation for the CN-LR820DFC-type card slot explains that the map SDHC card should be inserted correctly and fully into the dedicated map-card slot. The card should be inserted with the label facing upward and the cut corner in the specified direction.

Step 5 — Allow the Navigation System to Read the Card

After installation, allow the navigation system to initialize and read the map data. If the navigation continues to display an error, further diagnosis may be required.

What is CN-LR820DFC?

CN-LR820DFC is a Panasonic navigation model used as a genuine Subaru navigation system in the 2016 model group. Panasonic officially lists it under its Subaru navigation information.

What type of SD card does CN-LR820DFC use?

The navigation uses dedicated map SDHC memory card media. Panasonic’s documentation specifically describes the map SDHC card for this navigation family.

Can I use a normal SD card?

A normal blank SD card should not be treated as a replacement navigation map card. The navigation requires appropriate map media and map data.

Does CN-LR820DFC support map updates?

Yes. Panasonic’s official Subaru information provides a map-update application process for the 2016-model CN-LR820DFC.

My CN-LR820DFC says the map card is missing. What should I check?

Confirm that the correct map SDHC card is installed, check that it is inserted correctly, and confirm that the navigation model is actually CN-LR820DFC. If the card is damaged or unreadable, replacement may be required.

Can I use a CN-LR820DFA card in CN-LR820DFC?

Do not assume that different model numbers are interchangeable. CN-LR820DFA and CN-LR820DFC are separate navigation model numbers. Match the map media to the exact navigation model and applicable map version.

Is CN-LR820DFC a Subaru navigation?

Yes. Panasonic’s official Subaru information identifies CN-LR820DFC in the 2016 Subaru navigation model group.

What if I do not know my navigation model?

Send JapaneseNavi a clear photograph of the navigation model number or the original map SD card label before ordering.

Can every Subaru use this card?

No. Compatibility depends on the installed navigation unit. The vehicle name alone is not enough to determine compatibility.

How can I confirm CN-LR820DFC?

Check the model number printed on the navigation unit, original map SDHC card, vehicle documentation or navigation information screen. The required model should be CN-LR820DFC.

JapaneseNavi provides information and navigation map SD card solutions for Japanese-market vehicles and factory navigation systems.

Our product pages are organized around the exact navigation model number so customers can identify the correct map media instead of choosing a card based only on the vehicle name.

For CN-LR820DFC, this page focuses on the Panasonic Subaru navigation model, map SDHC media, map-card replacement searches and common navigation-card problems.

If you are unsure whether your navigation is CN-LR820DFC, send JapaneseNavi a clear photograph of the navigation model number before ordering.
