Images

The ECU images below are intended to get an idea and to show of which ECU it is. Furthermore, they could help if the question of the arrangement of the components is in the room after too fast disassembly or desoldering. The most frequently asked question in this context is:

"Where is Pin 1?". The photos shown can not cover all of the ECU revisions, so they should be seen as examples.

For V1, V2 and V3 there is a difference between version in the VW parts system and the display on the RNS315.

Press the setup button and hold for about 10 seconds.

The service screen appears. Select "Versions" now.

The last entry is the name of the map. For example "EUR_E_V8".

Perform map update

First of all organize the right SD-card.

Insert SD-Card with corresponding navigation data.

The RNS315 checks the SD-Card.

If the SD-Card is still virgin, the RNS315 asks if the SD-Card should be assigned to it. After assignment, the SD-Card is permanently married to the RNS315. And can no longer be used in another RNS315.

If you want to copy the data from the SD card into the RNS315, press "Install".

With "Use SD" the RNS315 directly accesses the navigation data of the SD-Card.

However, you should not do this because the navigation is slower and the SD-Card slot remains occupied.

That is why we choose "Install".

The installation takes about 120 minutes. There is no problem to switch off the ignition or the radio during the update.

It can happen that nobody is on the vehicle at the end of the installation. Then the RNS315 asleep again and no one sees the success of the installation. If the RNS315 is switched on again, the message "Successfully installed" no longer occurs, but the RNS315 wants to reinstall (overwrite)) or use the card immediately. Now just remove the card and everything is fine.
