Radio issues

[plien69]

I believe that people who have Premium see "Logic7" somewhere in their audio settings.

I think your Service Guy might be wrong. There are three different Amps used in 1ers, these are all documented here:

The three Amps are "Stereo", "HiFi" and "HiFi Top", of those only the HiFi Top system uses the MOST BUS, both of the other two Amps are affected by the problem documented here. Now .. according to the document I referenced, the reason they need the MOST BUS in the Top HiFi system is to handle DSP signals from the HeadUnit.

In NA the "Premium Audio Option" = "Top HiFi" , and other than the hidden better speakers, and the hidden hi-power Amp, the Premium System has Logic 7 DSPs. As already mentioned in this thread the best way to spot if you have Premium Audio, is to check if it has DSP support.

Therefore, if you do not have the DSP soft-button on the BMW Professional Head Unit's 2-line display, your stereo does not use MOST, and is vulnerable to the problem documented in the Service Note.

Finally, as the RAD2 system need to know if there is or is not a MOST BUS in play ... I would not be expecting a fix to this problem any time soon. It's been around since 2006 on the E90's so don't hold your breath.

Hi-Fi is the base radio. Premium Hi-Fi is how the Logic-7 system is listed on DCS.

RAD2: If you hit the "♪" button and scroll over, you'll see the L7 presets.
CCC: Logic 7 should have its own sub-menu on the audio settings.


If you're not sure what you have, you can PM the last 7 of your VIN to me and I'll check DCS.

ahhh... see i didn't think the base radio was called 'hi-fi'. i looked in all the settings, and didn't see anything about L7.

that stinks this has been around forever. that music as you're pulling out of your driveway gets you all geared to go, and then it mutes out a couple of times and ruins the moment. eh, as is life...
