hey!
I just recieved my new android headunit for my car.
just wanted to share my experiences so far, i did not have the time to fit it into my car until now.

the CPU seems to be a RockChip RK3066 and not the RK3188 stated in the descriptionn in aliexpress.
but anyway its seems to be fast enough.

- root was possible with KingRoot (4.8.0), will try supersu-me
- CopilotLive Europe (offline-Navigation) works, hat to pull the apk from my phone though.
- soft-bricked the device once already :cyclops:, restore was easy with a backup image on microSD.
- nova launcher (prime) works
- android seems to be pretty much stock
- google play store works, some apps cant be loaded though, i guess its DPI-related...

i will keep you updated on FM, installation and so on.
plus i will post my own images soon.
thinking about installing a 2,5-jack-port for an external microphone ... what do you think?

cheers!

most of your questions were answered in my original post.
gps - yes, including external antenna.
3g tethering - you mean use you phone as a WiFi-Hotpot? No, havent tried that. the unit is still on my desk ;)
play store works, just some apps are being blocked. for some i was able to transfer the apk from my phone to the unit.

hope this helps a little!

it's possible to have some answer ????
because i dont understand why i 'm register here ....
all people stay on the same post and the same answer ...

OK sorry for my late answer.
there are 2 firmware-images available, the newer one does not work for me (doesnt flash/boot)

my current problem is BT-related as well, the headunit cannot find ANY bluetooth device... tried phones, tablets.... nothing.
it seems the BT is not really embedded in the chipset but connected through some non-standard-interface, so no hardware-detection-tool recognizes a BT interface.

I have contacted the seller about this issue but got no response until now.
maybe thats what you get when you buy directly from china :(

ii have been following the thread on 4pda wor a while, of course just through the google translator so i cannot post anything and registration does not seem to work for me.

but basically the sound quality cannot be improved due to a hardware design fault.

maybe a solution turns up some day, i for myself decided not to worry about this anymore. the money is gone but i was already expecting something like this but gave it a shot.

one more thing @caraudio30000: you are too impatient. if anyone reads your posts and has something to say, he or she will answer. trust me. cheers!

Rockchip Rkpx3

Just bought a Rockchip Rkpx3 (Chinese car Android Player) yesterday from a local car accessories seller in Dhaka, Bangladesh. They imported it from China but the box doesn't have any name or logo and the seller said it's non-brand. However, when I connected to wifi with mobile hotspot and signed-in with my google account, playstore recognized it as Rockchip Rkpx3.

Long story short, although I had suspicion about the quality and longevity of the product which cost me about 200USD, after installation it seemed to work just fine. All the features including bluetooth, g-maps, wifi, cd/dvd playback, usb to android phone connectivity, external micro-sd, aux etc. works all good. I bought a rear camera as well with the player and that works fine too.

Android 5.1.1 (doesn't have any upgrade option though)
I didn't root and probably will not root in the future.

Don't know much about the firmware and stuff though as neither the box nor the user manual has much written on it except the features and which icon does what. Yes built-in gps works fine with g-maps and voice navigation was perfect. Although not possible for me to use the stock navigation app because Bangladesh's map (navigation purpose) is not available anywhere in the Internet LOL!!

All together, money well spent I must say. Was playing youtube all the way to work this morning :)
