I've taken note of the key phrase 'OkMap Desktop 17.11 download the last version for ipod' and extracted relevant information from the provided text.

It appears that OkMap Desktop is a software application, and the latest version available (as of the time of extraction) is OkMap Desktop 17.11 (also referred to as '圆4' in some contexts).

Regarding compatibility with an iPod, I found no specific mention of iPod support in the provided text or key phrase. However, based on my general knowledge, OkMap Desktop seems to be a desktop application designed for Windows operating systems, and it's unlikely to be compatible with an iPod directly.

If you're looking to use OkMap Desktop on your iPod, you may need to consider alternative methods, such as:

1. Using the app on a compatible Windows device and then transferring data to your iPod via USB or wireless transfer protocols.

2. Exploring other mapping or navigation apps that are specifically designed for mobile devices like iPods.

Please let me know if you'd like more assistance or guidance on this matter!
