I lost my original account so had to make a new one. Havent been on for a while. I got unit off ali express, ill post seller link if its allowed. Some guys on reddit post about it but leave no info, avin has one (x3 hack). This is the z4 non factory nav version with correct base. If you have factory nav, its nearly double the price, the connection are different, do not buy the same one.. it will not work. From other users, avin is working on a navigation version for z4. Also a lot of places sells the x3 model for z4, you get longer base, not shorter ones and it over laps to the dash.
Basically someone posted photos and leave no notes, so I did the research. Unit outputs into aux, if you can't live with that, this isn't for you. I use this specially for waze, I can't stand traffic. PX6 is the oem tablet code, lots of people makes it but only a few with z4 bases. PX6 RAM: 2gb/4gb/8gb (no good). Flash: 16/32/64 and optional SD Card, 4/6/8 (no good) cores. Its basically android tablet, more memory, more cores run better. I got the 4 core, 64gb memory, load more apps, etc. The 8gb/8 core is what I really wanted but many seller told me its not compatible with z4, I dont see how but there is some 'muc' programming that makes it talk to the car, I didnt want to mess with that so I just got the 4gb/6 core. Performance is good. Waze runs well on it, its also android 9, the older 6/7/8 had issues, lots of fixes in v9. Works out of the box. Basica install is unplug your radio, use the y cable and plug everything in. I ran with it without cutting dash to make sure it works well before I commit.
Cutting dash is hardest, that part took 2-3 hours, trying not to damage the dash. I'm also swapping trim so I pull out all the trim at the same time. I believe you can run the gps wires behind the trim area, that whole location is empty. I punch a hole by the passenger door where the gps, fuse tap usb for dash cam, and rear cam and front cam will come in and out of. Working on the front camera. The HD camera I got off ali express came yesterday. I just did a quick test, one I figure out how to run the wires, Ill post more photos.
