CAR AUDIO SOUND CONNECTION

First of all, I made a mistake and didn't do as much shopping around as I should have, but this guy was in town and I wouldn't have to drive my car an hour to Kansas City to get a radio installed. Also, I was trying to use in town business, because, in general, I want them to succeed. This same radio was on sale at Best Buy for $479.99 plus installation. The installation looked fine. One could tell the air vent at the top the dashboard was a little askew and the insert surrounding the radio looked tight, but it was flush with the rest of the dashboard details. The installer also left several grease spots from his head on my windshield. All these things I could have dealt with if my radio worked. However, I was receiving only one radio station well and about three stations with light static. On my previous radio I could easily receive stations from both Columbia (about 70 miles away) and Kansas City (about 50 miles away). I was getting zero of my previous 16 presets. As I was driving to work, I used the scan button and it went through every single station, and could only pick up one. My CD and iPod connections worked well. I did ask the installer if it would be possible to put the axillary cord through the middle console rather than through the glove compartment (that's where my old one was), and he said "no". I haven't had anyone look into this yet, as I am still recovering from the cost of this disaster, but I feel like it could be done. After discovering I had virtually zero radio stations, I took it back and had him look at it (I thought maybe it could be user error). The installer said he knew he had plugged in the antenna, plus the dashboard was "a pain in the a** to take apart" (very professional language). He manually found some stations (the one good one and some very crappy ones) and told me that he preset several stations for me that he found easily. I took his word for it (I thought I was right about user error, naturally) and went home. The next time I drove the car, I attempted, again, to find stations... unsuccessful. I also noticed that where the surrounding insert looked tight, it had snapped into two pieces. I WAS NOT going to take my car back to him; he had lost my trust. I ended up taking my car to a body shop to replace the plastic surrounding and, even though it's not their specialty, take a look at the radio. They couldn't find anything wrong with the radio, it WAS plugged in to the antenna. The plastic part cost me $50 dollars. Then I took the car to Best Buy and he had to install an antenna booster. Best Buy also told me that if there were any issues in the future with the radio it would have to be reprogrammed because the installer did not program it correctly. Best Buy charged me $50 for the booster and service. When it was all said and done, the installer may not have been totally in the fault, but if one's job is to install radios, I would hope you would make sure it works before the owner receives it. That's good business practice.
