And not to leave us luddites using Android devices befuddled and envious, there are several that will do the same for us. AAWireless, Motorola MA1 and Carsifi. 718 headunits that don't support AA can be hacked to add the feature. Search the forum for semaservis1108. He, and others, do it remote via a USB flash.
The "T-Box Mini", another option, is made by the CarLinkIt company referred to by the OP. It is, essentially, a wireless Android Auto hardware box that connects to our CarPlay capable PCM. It also functions as a full Android tablet with the PCM functioning as its screen. Twice the price of the dongles but bypasses the need to hack the headunit
I have the carlink3 and have an Iphone - it works splendidly and as it should for our cars and there are many/many threads on this same subject within this forum.
The new carlink4 offers more and or better Andriod connection - from what I can see and others users here with Andriod have all advised how that has then transformed their cars.
For me personally, I now use this almost solely in my 718, music, maps via WAZE, dictated and read-back texts etc etc.
There are literally hundreds of different dongles out there, all stating they do the same, all varying in prices hugely. The only reason I went with this version in the end was all the positive reviews within this forum and I have not been disappointed in the slightest.
Hope this assists in some small way.
