Custom Post Types, Geo Location, single google maps and category/archive mashup

Hello,
I tested a lot of google maps plugin in the last period but i didn’t find the one which fit my needs: i’m looking for a plugin to add geolocation info to custom post types posts from backend and frontend (a form field) and showing a Google Maps object on single-custom-post-type and a mashup on archive-custom-post-type or a category pages, better if i can filter the mashup, search for posts, etc.

Does someone know a good plugin? I hope i don’t have to code it from the scratch.
