Anyone here with a CIC with DAB+ tuners?

[jockyw2001]

Hey there,

In my E88 (2013) I retrofitted a CIC (Professional - 2011). It has two DAB tuners but unfortunately not DAB+ compliant. DAB+ is a later version of the DAB standard and BMW introduced CIC with DAB+ tuners in 2012. As far as I know the tuner hardware is still the same: MICROTUNE MT1503EDC based on a Atmel ATR2732/40 chipset (datasheets attached, and only the front-end/baseband chip firmware was updated. I am trying to find a software method to dump the tuner firmware flash chip.

My questions to you are, does any of you own a CIC with DAB+ and is willing to share the qnx dump with me for research purposes? I don't care whether it is a E- or F-series CIC, it seems both are nearly identical, at least for the tuner hardware.

One more question: I heard an E-series CIC can be fitted to a BMW F-series, but the other way around seems not possible. Is that true and what are the reasons for that?

Best wishes,
JockyW

Hmmm DAB in Australia has always been DAB+ and BMW debuted DAB in Australia in May 2011

That would explain why the hardware has the capability but may need software/firmware to make it work.

I’ve coded mine for DAB+ but not had a look to see if it actually has the connections for the Antenna

 

[jockyw2001]

I also coded it for DAB+ and the antenna connections for the 2 DAB tuners are there as well the yellow one for Band III and the green for L-Band. In my region there are only DAB+ stations and I always get "no signal". I'm pretty sure a MT1503EDC firmware update will do the trick.

I'd appreciate if you could check your unit has working DAB+ tuners.

 

[aus335iguy]

I’d like to check too but I’d need to connect a know good DAB antenna to be sure of that....
can you suggest something cheap and easy ?

 

[aus335iguy]

Actually I should probably check for the connectors first eh ?

 

[jockyw2001]

Yeah to begin with it should have the green/yellow connectors. This antenna will work at least for testing things.
If you are proficient using inpa or tool32 it can also be checked if your unit has dab tuners.

I have INPA but would need step by step instructions. It’d be easier to just look at the back of the thing, if I do I’ll get the antenna

 

[aus335iguy]

Also that connector doesn’t look like anything I remember on the back... you sure that’s correct ?

 

[jockyw2001]

see the attached pics of the rear-side. The plug type is called FAKRA

and yes the linked antenna has a SMB plug so you would need an adapter cable. For testing you could also use this antenna with FAKRA plug

I have e and f series cic with dab+, which files do you need? Im also interested in the e/f difference, the Hardware Looks very similar.

Hey Jockyw2001 did you figure this out? i too have the cic with dab and not dab+, tried to set the coding to dab+but no signal.
how about a i-level update for the cic? will that work?
