[QUOTE="ignorant1, post: 8229062, member: 659635"] Keep-Hope-Alive: Thank you again for the help. I truly & SINCERELY appreciate it! Although I’m an (old) amateur, I actually try to do things right – I solder the wires & use heat shrink tubing. I try to keep things orderly, but at your suggestion I did group things and used a lot of tiny zip-ties to clean up the install this morning. It looks much nicer! I also re-confirmed that I am getting voltage out of the HU for the antenna motor lead and there is also another lead for turning on an amplifier. Both work, and I've tried using both as sources of 12v for the antenna amp. (not at the same time - duh! [IMG]//content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif[/IMG]) I am using an adapter to go from the German (Euro style?) antenna coax plug to the antenna input in the HU. I have two different antenna adapters, and they both produce the same results, so it’s not that – unless they’re both bad, which is unlikely. I purposely tweaked around at the coax plug trying to see if I could perhaps get a temporary connection (assuming an internal break or short), and nothing changed. At first. While driving this afternoon, after doing NOTHING, the radio spontaneously started getting tremendous FM reception again. Weird. So something is intermittent; the question is what. I have to question if the factory antenna amp could be intermittent? Or do antenna amps tend to fail in a permanent fashion rather than act flakey & intermittently? I went to a local car stereo shop today to see if they had a coax splice for the small diameter coax (75-ohm) used in the factory harness, but no such luck. My idea is to take the antenna adapter that has about 10” of coax and cut & graft that onto the factory coax. That would at eliminate using any adapter and get rid of the original plug and the last few inches of coax. I’m not sure where I can find a splice for this thin coax.
