PLEASE HELP ME FIND A GOOD CAR PLUG FOR MY iPHONE

Question

Alright guys, I have been through 3 different plugs to connect my iphone to my car to play music, and I am a bit ticked. So i figured I would ask the Apple Discussion Boards so you guys can tell me the best audio/charger combo for my iPhone. Here is what happened with each of my previous plugs...
The first one was just a regular ordinary headphone plug that plugged from my iphones headphone slot to my car's auxiliary slot. It worked for a while but then the audio only started coming out through the right side of my car speakers occasionally, and I know for sure it is not my car that made the problem because my radio and CD's play fine through both speakers.
The second one is a "Kensington LiquidAUX Auxiliary Car Kit with Remote for iPod and iPhone". First off the remote that it came with didn't work properly. But here comes the worse part that is so annoying. This problem got progressively worse by the way.... a lot of times the plug would think that it unplugged itself for some strange reason and the music would stop as well as the charging, but then 1 millisecond later it would think it was plugged back in, and although it starts charging again, the music doesn't play again until I press play. Don't tell me to make sure it is plugged in securely because trust me my friends, I have tried everything possible to get this to work. Keep in mind I am driving...so it is a very bad idea to be messing with my phone to press the play again. And lately it has been getting so bad that I actually have to unplug the plug from my iphone and then plug it back in and press play, which is incredibly annoying. This happens about once a minute OR MORE now a days. Also, it makes a really annoying "whirrling" sound whenever I am using it. By the way, I even turned Airplane mode on, and the exact same problems still happened. So a summary of this: this audio/charger combo is a failure.
My 3rd plug I decided to try a normal headphone to aux plug again like the first except this time by a better brand, Griffin. But oh wait, the exact same problem happened that the first one had.
Ok guys, so what I really want for you to do for me is PLEASE HELP ME FIND A GOOD CAR PLUG FOR MY iPHONE.
Here is what I am looking for in my plug:
Plays music through my car's speakers AND charges at the same time;
I would prefer if it wasn't an FM transmitter because those tend to lose audio quality compared to direct plugins, unless you know of an amazing FM transmitter where you don't lose audio quality;
And finally, I want my plug to ACTUALLY WORK WITHOUT GLITCHES
Also, it would be nice if the plug that you refer to me, you actually own, so I know that you have tested it out before and that it works great.
Any HELP would be very much appreciated, thank you.

Answer 1

i thought about going the same route you did, but when I started looking at the prices of everything, I decided it was a better idea to just get a new stereo that can play and charge my iPhone.
After a lot of comparing, looking and price checking, I decided to go with the Alpine IDA-X100. This is a media player only device (no cd player built in) and it has been great. It has an awesome interface and dial setup that let's you go through your music just as if it were on an iPod. It even has a small color screen that displays the album artwork for you. My car has a factory BOSE system in it and the Alpine head unit even managed to improve the sound quality. Go see you local alpine dealer (or best buy) and check it out. The supplied cable charges the phone and plays music too. Your iPhone will give you an error message when you plug it in, saying that the accessory was not designed for iPhone, but if you just click no it works great.
