Default Arliberator GPS Problem using xperias


first, sorry for my bad english.

I am using the app arliberator with my xperia ion, before i had an xperia p and the same problem.

The GPS signal stops every 3-4 seconds for 1-2 seconds and again and again and again.

I changed now from the xperia p to the ion but having the same prob.

I tried to change to cyanogenmod 11, but this is not compatible with the integrated xperia hdmi ports

In my iphone4 with the appradio 100 the gps works perfekt, but i dont like the iphone

A Member here called "=JSG=" wrote that it would work perfect with : Rogers Rom 4.0.4
But i don`t if it works 100 with the gps.
but i cannot contact him because i need 10 posts first

I would be very grateful i someone could help me

best regards
