Installing vintage radio in GTV

I recently purchased a vintage Blaupunkt Frankfort radio for my GTV-2000 and will be attempting to install myself. Question: What should I use for my radio's power source - a switched or constant power source? And what is the best way to find the right hot power source wire to use aa well as the ground wire?

Any suggestions would be appreciated!

Since nobody answered, some general advice (as I don't know GTV 2000 well):

1. Use a switched source. preferably for accessories (Acc).

2. Consult the owners manual which fuses on the fuse panel are switched, then use a multi-tester or test light to confirm which one(s) relate to Acc power. Remove that fuse and test again to see which side is battery and which side is load, then follow the wires from the load side and locate one that goes near the radio. Usually radios have a separate 5x20 mm fuse in the power wire. Also, if the radio picks up noise from the ignition, you may have to install a noise suppressor.

3. The enclosure of the car radio is usually metal that gets grounded by installing a support bracket at the back to eliminate stress on the front fascia and threads for the control buttons. So, finding a good ground is more or less a mechanical problem of finding a good location for weight support.

A scanned copy of the user manual can be found on this site.

I've seen noise suppressers wired on some cars to stop audio interference from the ignition firing.. I can't comment further from lack of experience but you might want to investigate that subject with others. just a heads up. There might even be mention of it in a Blauplunkt manual which I am sure you can find on the internet.
