Android head unit google maps is slow

I installed new android head unit on prius 2010, 4gb ram and 4 core cpu, 32gb. Everything - interface , music, video, bluetooth, radio works fine but google maps loading is very slow and laggy, I checked ram and there is only 400mb free ram , I didn't installed any app on android. Is there anything that I can do?

 

I installed android head unit for rear/parking camera, I do not know how would ipad work, so I prefered head unit.

This head unit doesn't have any warranty and also it's chinese and has not any original brand.

I use android phone(s) to connect over mobile hotspot with fast internet. 4g/4.5g/LTE , I don't sync anything other.

Yes I tried google maps on my phone and everything works good. On head unit it takes about 2+ minutes to load and start trip on google maps. I tried Google Maps Go on android head unit and it's little bit fast. Also I have little GPS Coordinates app and works fine, when I run it shows correct coordinates in a second. I installed couple device info apps and it shows only 400mb free ram from 4gb but every other thing in interface, music, video, bluetooth, back camera works good as I wrote above. But also I think this info apps get wrong information from head unit sensors, because it shows 7.4 inch display size but I measured with ruler and it's about 9 inch, also I bought as 9 inch . Is there any way to install other android os or is it to risky?

 

Yes you are right, but I paid only 200$ for head unit, rear camera and installation, head unit is new. Original head units cost 600-700$.

My head unit is/was new. Also as I mentioned everything work well beside gps , which is slow but it works anyway. Steering wheel buttons work too. Also it has cooler fan. I looked the website you suggested, I think it will cost me two times more. But thanks for suggestion.

 

They are the one that installed it, yes, but it is not any lie about slow gps , I knew that this not original head units have such problem but I wanted to know if there any way to resolve this problem. Right now I have not video about gps but I have some photos about this head unit. I know that it does not have high quality but price/quality ratio is normal I think. https://media-upload.net/uploads/q06oAEx9gv48.mp4

 

Finally I returned and replaced my android head unit, also I added about 40$. So what happened, I checked RAM on my old head unit and it showed only 350-400mb available memory and I came to the conclusion that it was not "real" 4gb ram, it was 1gb, because of this there was only 400mb usable ram. Also there were only 10 gb free storage out of "32 gb", but in really it was 16gb. About CPU was everything correct. So, my unit was 1/16 and not 4/32!
Now I replaced old unit to the new one and it has real 4gb ram, which shows in several apps (CPU-Z, AIDA64...) free 3000-3200mb for usage. Also it has 8-Core cortex A53 2.6hz on all cores cpu. What can I tell about storage is some apps show 32gb some 64, still to determine , but I don't have problam about it.
In short, on my new head unit everything works very good , include gps. Only one problem is that reverse camera has not good quality. I didn't replace this camera, it's same one, but it had better quality on my first android unit than on this new one. I have selected ntsc (and others) but same quality, it is not big problem but would be better if it was solved.

 

Thanks, yes 100% they lied about ram and storage. I think android system was heavily modified , because when I loaded system it showed android 13 during boot, also in some apps it had shown android 12 and also in other android 8. I think that was because of system information manually manipulation, e.g. locking ram value 4gb in system settings or third-party apps that ill-informed user can not detect this lie, that there were no any 4gb ram. "Available ram" value is difficult to hide because it's constantly and randomly changing, but everything happens. Also user may suspect why is only 10gb free storage space if the storage is 32gb, where is 22 gb (at least 15, if we exclude operating system maximum size)? It's like this because there is only 16gb real storage, about 5-6gb is occupied by system files and 10 is free, that is real.

 

I bought it to Georgia, not in US. But this head units are from china, exact seller unforunately I don't know.

 

yes, it's also possible to buy from US anything(which is legal) to Georgia.

 

I tested everything and now I have two problem (I think solvable), first, gps sometimes has low accuracy especially when windows are up. If anyone knows, where can GPS antenna be installed to have good signal/accuracy?
Second problem, I have installed JBL adapter but sound only comes from front speakers which are near windscreen and I think there is very very low sound from front door speakers. Is there anyway to resolve this problem?
