Hi all, Joined the forum looking for some information and advice – have a 2005 Toyota Corolla wagon and looking to upgrade the CD player to an aftermarket unit (Android) so that I can use GPS and reverse camera. Been looking at Eonon and Kenwood MT 3200 or 5020 as confused by the ones on Aliexpress/Amazon and ebay, will be getting a professional to install. https://www.eonon.com/Android-Car-GPS/Vehicle-Specific-GPS/Eonon-Toyota-Android-11-Car-Stereo-7-Inch-IPS-Display-Car-GPS-Navigation-Wireless-Apple-CarPlay--Android-Auto-Head-Unit.html Here are some pics, measurements if I got them correct. EONON support suggest R67 (for 200mm x 100mm) but advised that is not compatible with JBL audio system. Does anyone know how to check for this JBL audio? I assume check the speakers etc. I am not an audio person and have no idea, bought it as is, 2nd owner and owned it for 13yrs. If any members have updated their head unit EONON or other brands etc, please post your experience. Thanks in advance!
