is the problem power or noise?

I'm finding it hard to believe that the "problem" is noise/interference and fixed by a supressor.

In the car, using the auxiliary position on the ignition (no engine or ignition components running), the GTM12 does not function (no traffic signal detected).

This evening, I have tried three different chargers.
Previously, it has worked with one of these chargers, so the problem is not consistent.

If I initially power the nuvi with GTM12 from my PC, everything works, with TMC messages appearing in a few seconds.

Transferring the nuvi & GTM12 to the car before it has time to switch-off, then connecting it to any of the three chargers, and it continues to receive traffic messages.

The problem seems to be that the GTM12 does not start when powered in the car (most of the time), but once it has started (using the PC) it then continues to operate correctly from any of the three car chargers.

I don't beleive that this is behaviour can be explained by a noise or interference problem.
