Hello All. I got mine installed yesterday -- first time I've done anything like this. I read through all the replies and noticed several folks have problems with their AC not functioning properly without unplugging that 32-pins plug under the glove compartment. I have '03 FX45 without the NAV feature. I did not have to unplug that 32-pins nor did anything with my glove box/compartment. However, there's a grey flat box that someone pointed earlier and it is located in the middle layer of the old radio head unit. I believe this grey box is the AC control? Anyhow, there are three plugs on it and I left this entire grey AC control box plugged in. Meaning, however it was installed by the OEM, I left it as-is and simply unscrewed it from the metal casing/shell. The AC controls both on the touch screen UI and the physical button on the new Android unit works fine. I get cold air, can increase or decrease the temperature and able to change the default celsius to fahrenheit.
All other features work okay e.g. Music, AM/FM, Maps, CarPlay and programmable steering works. The following three items I have not been able to figure it out.
1. My FX45 doesn't have OEM backup camera. My Android unit came with a backup camera and I have spent several hours but could not get it to work. I looked at several videos on Youtube about general backup camera installation and they mostly mentioned to tap the red wire that pig tailed with the AV cable to an accessory power source at the front of the vehicle. The entire Android unit, I don't see a red wire sticking out anywhere to tap a red cable into. When I back up the vehicle, I see a black screen split with the yellow lines but pretty much no image. At least on reverse, it triggers the blank video screen. [Major]
2. Static sounds problem. When CarPlay or radio plays, I don't hear the static sound. When no audio sources are active, I do hear statics or constant noise from the speakers. In one of the earlier replies, I saw someone figured it out by using a AV cable and tap it onto a screw to the back of the Android unit? It wasn't very clear on that user's reply but would be great to get rid of the static sound. [Minor]
3. My unit came with a dongle for cellular connection. I used an LTE SIM card and it didn't work and both SIM slots still indicate empty. Perhaps I needed an actual 4G SIM card instead? I thought LTE SIM card was backward compatible with 4G. [Minor]
It looks better than the OEM stereo but I mean it could be better for a $600 on an after market unit. If I can get item 1 above to work, which I labeled as "Major" then it would be great. Getting backup camera to work to me was important. If anyone has any tips, I'm all ears. I bought mine from AliExpress by the way.
Thank you for reading.
