Absolutely not! I think it's also important that we take the time and understand how the hardware is made up.

But I'm not a show off!

And it took a while before the shielding finally gave in... No idea if I ruined a chip or two. Haven't put together & tested the Navigon ever since.

But which chip remains the question! For as far as I can tell we have TWO GPS-capable chips in that device! The SiRF Atlas V has GPS integrated and the SiGe SE4150L is a dedicated chip.

Exactly. I came to that conclusion very early as the cable is way too thin to contain any IC/PCB. But where is the TMC decoded? The CPU/GPU may be the answer as (newer) CPUs often have FM-capability (FM radio) integrated.

Ah, see what the datasheet says:

"When combined with CSR Synergy™, this processor can be seamlessly integrated with CSR's Audio and Connectivity Platforms [...] CSR Synergy supports Bluetooth®, Bluetooth low energy, Wi-Fi, echo cancellation, noise suppression, FM receive and transmit and more[...]

So it's the SiRF-chip that does the TMC-decoding - via CSR Synergy. Oh, and that's a SOFTWARE solution!

Doesn't look hopeless to me anymore. If we can get some... dedicated people on to it. As CSR Energy is STILL in use up to this day. May also be interesting for some newer devices. At least to understand how navigation-software uses it to manage the hardware.

Update:
And the 40 Plus is still alive! But I had to resolder a micro smd-capacitator (0,5mm size) which I had accidentally "swiped" when I removed the shielding. Sound was also not working at first as the loudspeaker only LOOKED plugged into its socket but wasn't.

Now, question remains is there a WinCE 6-based navi with SiRF Atlas V and working TMC under iGO8? Let's find out...

Many navis use this chip, even some really cheap ones from China. I'll try my luck with a Medion GoPal-device (maybe the 4470?) as they are very common and have a dedicated community.
