My experience

Those coming from iGO Primo for iGO NextGen catch a disappointment but it's for a short time with the use realizes the NextGen has more advantages.

iGO Primo
IGO Primo "yet" is the crown jewel but not for long
The latest version for android is more stable and fast.
It has several years of developing skins, global_cfg, brandings etc therefore more visual and technical options for the end user.

iGO Nextgen
The visual panel and the options are more organized.
It is faster in every respect.
The TT-PRO works better than the iGO Primo.
And there are more services available eg: Climate, Fuel

Needs time to mature both skins as in the additional add-ons.


Best regards
