So the factory touchscreen started to fail where many of my finger pushes weren't registering or it would register but select the wrong buttons, apparently normal due to age and wear. So I bought and installed the latest and greatest G6 version from Phoenix Automotive and although the plugs and all were relatively straightforward, it was a huge pain in the ass to somehow mash that huge birdsnest of wires back behind the radio and actually shove the radio back in to the dash. Then came the second pain-point which was that audio, even with the factory amp and the amp switch defaulted to on, I was only getting a very low volume sound after turning it all the way up. Plugging in the factory radio and cranking it to full volume then reinstalling the G6 made no difference. What did fix it was turning off the factory amp option and leaving the AMP switch option on and then messing with the sound field delay screen to get the sound coming out just right, otherwise it sounded like an overly compressed MP3/4 or XM radio which in a word, is garbage. Then setting the EQ in the DSP options further enhanced the audio quality and now it definitely has more punch than the stock radio did. It took quite a while to get it dialed in so I definitely don't recommend it for any novice tinkerer. Now I just have one issue and maybe it's just a function of the newest G6, but from my understanding, the older PX6 worked just like factory in regards to the power antenna, it only powered it on when the radio app was selected, the antenna would go back down otherwise. With my G6, as soon as I turn the car on, the antenna powers up and raises no matter which function is selected. I tried turning off the power antenna option in the settings but it changed nothing. It's a minor quirk and I tend to be on the ocd side. Also, I chose to wire up a new backup camera because our factory camera is trash with low resolution that always washes out in low light situations and requires more work to wire it to the android unit than just running new wires to a much better quality 720p camera. Now the backup image is sharp and great day or night.
Lastly, the AC controls work perfectly, out of the box I had no issues controlling both the front and rear AC, works exactly as it did stock and the physical buttons on the bottom work exactly as they should, no settings changes necessary for me. What did require a settings change were my steering wheel controls, the up/dn buttons were reversed, a simple settings change in the system settings fixed that.
Having an Android phone, I primarily use Android auto and it functions just as it should as well. Played a few videos on Youtube and it played fine as well.
I also replaced the burnt out bulbs with LED bulbs in the diff-lock and antenna buttons to match the new head unit while I was in there swapping it to the new side bezels (which aren't the best fitting).
If anyone else has insights about the power antenna issue on these new G6 units for the 06-07 LX, I'd like to hear it since I'm at a loss and tech support has no clue what I'm talking about haha.
