Markos,Per the recommendation of others, I am providing feedback on my experience with @Enoz. I was disappointed with portions of my transaction. Particularly, Enoz did not notify me of critical information about the sale until *after he shipped the radio. He should have included this information in the ad, or at the very least informed me of the situation prior to shipping. I had quietly let this one go until Enoz posted his shed with 30+ radios in it. More below. There is two sides to every story as well all know. I was more annoyed with the process and conversation at the time. In retrospect however, it was the initial ad that was flawed. It is important to note that our entire conversation was pleasant. I was frustrated with the situation but Enoz and I were in close contact. I have it in bold below, but I want to reiterate that Enoz did offer a full refund, just not an alternative radio.
I ordered a Blaupunkt Frankfurt from Enoz back in August 2018. It was advertised with no fine print or information about the polarity of the radio. After paying for the radio and receiving the tracking information, Enoz says the following:
"One very important thing you need to know about the radio. The radio comes from an English MG and the wiring is different from others the "+" of the battery (power wire) comes on the chassis of the radio (black wire) the "-" of the battery (ground) comes on the red wire of the radio - Regards Enoz"
Now this was news to me, I reminded him that the radio will short out when plugged into the mounting bracket (which secures to the tunnel), and that the antenna is grounded to the body as well (also triggering a short). I ask if he has actually tested this radio in a car, or only on a bench. Enoz tells me that he has fully tested it on a bench knowing that this radio was different, and to "just be careful that the chassis of the radio is not connected to the ground of the car". He also told me that he spoke with his radio specialist, which told him that the antenna doesn't matter if it is electric. This is not the case, standard car antennas are grounded and you produce static over the speakers if they aren't. For those that aren't terribly familiar with DC power, you can indeed shield a radio that has a positive ground. The entire radio case is charged however, as is the face of the radio. This doesn't matter in a car with an entire electrical system is positive ground. On the other hand, if you have a positive grounded radio (non-standard) in a negative ground (standard) car, touching a screwdriver or your keys between the shift lever and the radio face will cause a spark. Any "shielding" that works it's way lose or falls off will result in a spark. Yes that is the case for any positive wire in your vehicle. We have all had shorts before and some of us have had fires. I don't know many folks who would knowingly introduce such a risk into their prized vehicle.
I asked why he didn't notify me of this information prior to shipping, and that I did not want it. He said that apparently he had "not thought about this". He said that was already shipped, but would offer a full refund if I could not have it repaired.
Note that one can change the polarity on Blaupunkt radios. The older Blaupunkt radios actually have a small blade that you can flip to change from positive ground to negative ground, or 12v to 6v. This radio did not have that.
Again, not being offered an immediate alternative radio, I told Enoz that I would check into changing the polarity. He did send the wiring diagram, which was very helpful. Enoz said that it would cost him 12€ to have this done, and he would refund me $25. I stated that it would most certainly cost more than $25, and I checked with an electronics specialist. The quote was $40-$125. Enoz did not want to spend more than $35, so he suggested that I send it back. Again, no mention of a replacement.
I said screw it and just fixed it myself. I am proficient at soldering but really didn't want to bust out a soldering iron on a radio that I bought from a well known radio vendor.
Here are my final thoughts on what I would have liked to have seen:
1. Information in the original ad that this was a reverse polarity radio, and the caveats and risks that this entails
2. Reminder once again *before paying for and shipping such a product that this is a reverse polarity radio
3. Immediately offer to replace it with another radio. You are a vendor with dozens of radios, ship the new radio ASAP.
4. Offer a reasonable figure to have the radio fixed *if the customer was willing to go through the hassle. $35?
5. Take a hit, we have all taken a hit on a sale, rectify the situation and grow your word-of-mouth-reputation.
Lastly, one could say that this was an honest mistake. Perhaps the seller did not understand the implications of the reverse polarity radio. This was known information - ahead of the sale. Also, we are not talking about a guy selling his spare radio that has been sitting in the garage for 25 years. We are talking about a professional radio seller, whether it is his full-time job or not. Enoz has 80 ads going at any point in time across countless car forums, and Ebay. He is a vendor. Vendors (good vendors) put their customer first, not the bottom line. I simply don't feel like this happened in my case, and felt compelled to share.
That's it folks!
