Review on 🚗 7 Inch HD Touch Screen Android Car Stereo with Navigation, Bluetooth, FM, GPS, WiFi, USB, Mirror Link, Split Screen, and Backup Camera by Marco Wilson

I decided to increase the rating to 3 stars because everything else is fine. I like stereo. Podofo tried to help and even offered to pay for the filters I bought to fix the problem. Unfortunately nothing happened. On the 12V supply line I installed a noise filter and semi-annular snap filters. You cannot use the speakerphone. The engine noise of my interlocutor is very bad. It gets worse as the RPM increases. It's not an ignition sound as I have a Deisle. (7.3L) I'm pretty sure it's the emissions from my injectors. I have no noise on my end. It's the same whether I make or receive calls. I like everything else about the stereo but I really need BT calls.
