2014 Fortwo Pure Radio Wiring

Hey there! New user to the forums (and new Smart owner!), I wanted to try and compile some stuff in a post because I found it was difficult to find information for my specific vehicle and ask a question.

However, since I purchased the vehicle used and either there's little information on this vehicle specifically or my google-fu is weak, this information should be taken with a grain of salt unless other people confirm it. Please don't ruin your car because of me

The attached image is what I've mapped out for my radio's wiring. For anyone else working on this, I've noticed:
  • There is a brown/black wire from the vehicle end that is hard to find info for. I found online that it is connected to parking for DVD/Navigation control (so you have to park to interact with the device?)
  • Many diagrams show that there are two black wires and two red/blue wires from the vehicle side of this harness. This only had one.
  • The 12v constant/ignition wire switching maneuver is still needed on this model.

Now, the big question that I would love to pick your brain about:

I've been able to get this radio working great, except for the radio reception itself being actually non-existent. I tested to ensure that this was a powered antenna by using a grounded probe: when inserted into the antenna terminal with the adapter, the radio would pick up flawlessly. I then double checked that it was getting power to the antenna by sticking a probe into where the harness connects into the back of the radio (12v amp -- blue/white wire), and it is being powered. I double checked that the antenna connection itself was making a good connection at the antenna terminal, and as far as I can tell there's no looseness or disconnect in the connection. Any thoughts on this?

Thanks!

Edit

So, turns out it was a loose connection in the wiring harness that connects to the back of the radio. Pushing the probes in to test for power was enough to make the connection while I was testing, so that was an easy fix. Problem solved

Thanks, jwight! I am happy to find a good community for this stuff.

Unfortunately, it looks like that information is behind a paywall! Probably why I didn't find it to begin with. Do you think a subscription to evilution is worth it?

Cheers

Absolutely! Every smart owner can benefit from a subscription; the best $15 you can spend. Next on the list would be a subscription to alldatadiy.com IMHO.

I have no relationship with or financial interest in either venture.
