(no sound)Retrofit from Hi-Fi to Logic 7 HK Bmw E90

rxg · 01-22-2023, 04:22 AM

Hello, I retrofitted from hifi to logic 7, I connected the amp via fiber cable, it communicates with the car, it can be seen in the inpa, I coded the navigation (mask2) on logic 7, I can go to the settings of logic 7 and they’re working, I connected the wires from the speakers to the amp (all the speakers replaced with those from HK), the wires from the hifi amp system to the navigation remained disconnected, being the connection via fiber cable now. everything seems ok, except that I have no sound. (m ask2 2008, logic 7 system 2010). can someone help me please?

you need to upgrade mask2 firmware to amp level or downgrade
amp firmware to mask2 level
there is well known no-sound issue that when you have pre-2008/09 car with logic and install CIC, you have to upgrade AMP firmware.

you need to have winkfpt setup working (filled with SP-DATEN) of the correct year
you may dig it here

or other multiple topics on this or another bmw forum
after that it is easier to downgrade HK amp firmware because it is small
the MASK2 firmware is much larger and will require 30-60 min of the programming , which require ICOM MOST interface, additional power supply
another way is to grab MASK2 unit with manufacturing date in 2009 from ebay, they should be cheap, because later it was replaced by CIC MID
CIC MID is also good upgrade
