Is anyone here can tell me that any IGO version can run on WinCe 4.2 Core? I have an AIRIS WinCe 4.2 and running Route66 SatNav and I couldn't find any compatible Ireland and UK maps that can run on my SatNav. The Map format was .prm? If I couldn't change the Route66 to any other GPS so where can I find the .prm format maps? Thanks.
