I would like to use swipe keyboard (app) for android in Igo Primo. Sygic is using default keyboard what android is using.

When i click on address of my contact from address book, phone offers me to complete action using: Maps, Navigator, Sygic,... but no Igo Primo You can change that

Primo is using the default keyboard as well, it is part of the lang.zip file, in content/lang folder.
About second question, wait for others to reply.

When you click on the address in contacts an intent is broadcasted, applications that can receive this intent will be shown by Android using the "Complete action by..." menu we've all seen millions of times.
if iGO isn't shown then it doesn't receive this intent, this is a matter for the developers of iGO.

So, how to set default keyboard??? I have many zip files in lang folder...
I have Lang_English-uk.zip
i would like to use danish too, i dont have file

But this doesn't look anything connected with my default keyboard, swipe.
How to use Swipe in Igo Primo???

For the Danish voice file, look at the language sub forum for "Variety of Primo voices".

Im not interested in voice file, but danish Swipe keyboard

As far as I'm aware you can't use a system keyboard, iGO uses its own internal keyboard.

Any chance those things are going to change?
Keyboard and navigating using contact list?
Igo keyboards suck

Only the developers can answer that question...
