Problems using IGO 8.3.5.193799 in Eonon E1025

Will someone help me? I have a GPS in the car radio Model Eonon E1025.
I installed this version of Igo 8.3.5.193799, The first time he gets everything right, but usually works off and on again it's an error of OUT OF MEMORY, depending on loading sometimes appears on "Data Warning" when loading or then in the "Start" will show when entering the program.
I've tried everything that is in sys.txt configuration memory, only to leave without the quotes values​​. Since I took the TTS voices. I could read everything I tried.
Does someone could help me to try anything else?

More often than not, the memory warning happens because your device is trying to load too much content at the beginning. I suggest that you remove the dem files, building files, reduce the area of speedcams, reduce the amount of maps, etc. The data warning is iGO converting the speedcam .txt into the files it needs to operate. This is a normal message.
