FAQ: Frequently asked questions about the Nissan Almera G15 radio

Is it possible to install a radio with Android Auto in Almera G15 without losing the steering buttons?

Yes, but this will require an adaptation module, for example, Pac RP4-NIS01 or Connects2 CTNI23. These modules convert signals from the steering buttons into commands that the new radio can understand. The cost of the module is from 2,500 to 4,000 rubles; installation at a service center will cost another 1,500–2,000 rubles.

Important: some Chinese radios (for example, Xtrons) have built-in support for steering wheel buttons Nissan, but the quality of their work is often poor - the buttons may respond with a delay or not work at all.

Why did the clock on the instrument panel stop working after replacing the radio?

B Almera G15 The clock on the instrument panel is synchronized with the radio by CAN bus. If the new radio does not support this protocol, the clock will be reset. Solutions:

  1. Install a radio with support CAN (For example, Pioneer AVH-Z5200BT).
  2. Connect a separate synchronization module (for example, CanBus Decoder).
  3. Set the clock manually via the instrument panel menu (hold the TRIP 5 seconds).
How to connect a subwoofer to the standard radio of Nissan Almera G15?

The standard radio does not have RCA outputs, so you will need:

  1. Buy linear converter (For example, LC-2 from Kicx).
  2. Connect the converter to the rear speakers (green and purple wires in the radio connector).
  3. Output the signal from the converter to the amplifier and then to the subwoofer.

Important: in Almera G15 the rear speakers are connected via an amplifier, so it is better to take the signal for the converter from front speakers (white and gray wires).

Is it possible to install a radio with a large screen (9-10 inches) in Almera G15?
