I have found the following map really useful, it is clear, all road marked, also if you look carefully you can see roads that will later appear, yet to be discovered!:D.
I am not sure how often they update the maps but this one is the most recent. covers Karagozler thru to Patlangic down to Calis, Gunlukbasi Catalarik, Koca Calis upto the start of the new road Karagedik.
Yesterday more shops had them on sale, the front street where the banks are Finans, Garanti etc.. or the birthday card shop, 5YTL
cover.
Just a snippet
