I want to upate my ICOM A2 but i have no poweradapter.

Is there a 12v power adapter for ICOM A2, or is it only possible to connecting with BMW.

2 methods I know round this issue:

1: Plug ICOM into any car with 16 pin OBD port and update it. Pin 4-5 Earth and pin 16 Terminal 30 seems to be standard on every car I've seen.

2: Get 12V PSU, cut OBD connector off scrap car. Connect OBD connector to 12V PSU and power up ICOM on bench, then update it.

However I am guessing you have an ICOM to diagnose BMW. Why not just wait until next time you need to diagnose a BMW and update ICOM before starting job?

1. Confirmed I wasn't sure i could do it using a non BMW, but I successfully updated my ICOM NEXT using a Benz OBD port as my power supply today since my BMW has been in the bodyshop for a month now.

I use a 12v power supply from a CB radio

1 & 16 to 12v
4 & 5 to ground

I modified the ICOM C, opening the OBD socket screws and put 12v to pin 16 and then link wire to pin 1, pins 4 & 5 already linked so soldered ground here.

NOTE: Pin 1 (Terminal 15) is not really needed, but I put meter on these pins and calibrated the eeprom so the ICOM Clone was reading the correct voltages as per my Fluke Meter.

Buy a ODB plug and a 12V supply, must have minimum 2 ampere.
Cost not more than 10€
