OK Boki, I finally got it through Slovakia, Will try it later.
Back again having had a few tries.
On the U20i I got the Unexpected javaclient problem as before unfortunately..
On one of the E10i I get "X not installed"
On the other E10i it installs and appears to be working OK, Super great as a shirt pocket navigator!
I had a few Xperias I collected a few years back, in fact I still use an st15i as an everyday cell, it runs Android 5.1
and is not a problem to carry around. The U20i I foolishly offered free to a friend with the promise of a working iGO hence the problem.
I will try a few things on the U20i, I also tried on a rooted one too, but it is the same.
Anyway thanks for the soft and advice.
Sorry I had not looked at your last and did not realize there was a vpn on GPS power!

Still going crazy with this U20i Android 2.1 unrooted. Have tried all versions that I have found of iGO for 320x240 for old versions of Android but almost always I get the dreaded " The application iGO (process com.navngo.igo.javaclient) has stopped unexpectedly. please try again, with force close box which just returns home screen.
Last ones tried NG A 1.6+, iGOMyWay_v8.4.3.179971, iGO Primo (Explay Infinity II) 9.6.7.318746 (Jul 31 2013) 320x240, plus a few others! On the odd occasion I did see data not found but nothing I changed in sys made a difference. ???
