My 2010 has the jbl sound system and navigation and I want to upgrade my screen to android auto and not loose the JBL and use my exsisting backup camera. Which units will work for me?
None; Your head unit is incompatible and won't even do Apple Carplay. Android Auto was only available on gen4 base models; higher end models was Carplay ONLY compatible. That may have changed for the gen5s. I don't know. The cheapest and easiest way to get android auto into your car is through a separate screen; like the one below.
The statement made above is incorrect. I just did an install in my prius with an android unit called Smarty Trend. High priced tho and a dice roll if you do not get the correct harness sent to you. Only good communication is through Whatsapp. You can use factory camera and SWC. Will work with JBL system. But.....you can get it done for way less with cheaper android units for sure.
