Thanks again Tiger.

That is a good point. I'll have to get a wire with a fuse. Remember that mine is a diesel car and does not have the hazards of gasoline.

At the same time, when you do this, you are providing 100% power all the
time to your GPS... which will not allow the GPS to turn off
automatically when power disappear. So, you will drain your battery
power and if you got an old battery, soon, you will not be able to start
your car up.

I don't think so. Using that battery+ connection wire was only to find the contact point of the copper bulge in the ash tray. I did find it and I am not using that wire any more.

The Garmin and the radio shut off with the ignition key.

The GPS is not even installed yet. It seems that the wire with the red plug was intended for the cigar lighter and the female spade connection for the radio. But the radio is already connected. It and Garmin shut off when the ignition key goes to the off position and the drain of the Garmin is not likely to be as strong as that of the radio.

It appears that I have now to complete the job by getting a wire about 6" to 12" long and with soldering small "spades" at the ends of the wire. That should not be too difficult.

Do yourself a favor at this time, let someone who knows about
electricity install it for you. You are risking car fire and problems
down the road at this point.

I have done wiring and rewiring in a number of areas in that car and previous cars and I have had no bonfire yet. I have already called many service garages in my area and told them about the problem. Not one was interested and none had any experience of satellite devices. I'll have to try the MBZ HQ for more info.

Hope you had an enjoyable weekend :-)
