differences between 255 and 255 music

Other than the obvious of the music version supporting music, what are the technical differences between the 255 and the 255M?

I read somewhere that the music version has WiFi but non-music does not. Are there any other differences? For example in the amount of flash storage or RAM in the watch? The specs on the Garmin website state both have 4Gbyte memory/history but would like to double check that's not an error on the website.

I'm currently using a 645 (music) and looking for potential replacement as the strap lugs have started to crack and I suspect not going to last much longer.

I don't use the music feature at all so non music version is probably fine. I do use course navigation a lot (pre-planning courses on Komoot) and regularly tinker with connect IQ apps so wouldn't want to be restricted by a small amount of memory.

Thanks!

I have the non-music and it seems like it has a 4GB flash (some 3.x GB free when I looked at the filesystem via USB on a computer).

For other CIQ limits you might check:

I think I see some differences though I don't know if they are significant. The music model seems to support 768KB watch faces and widgets while the non-music supports 512KB. And of course the music model supports audio content providers which the non-music doesn't list at all.

I don't think mine supports bluetooth headphones at all. So, you also cannot get audio prompts during activities, unless you bring along and pair your phone. Then, audio prompts can come via the GCM app.

Thanks for the information. This is exactly what I was looking for.

It looks like the differences between the 255 and 255M are not as significant as those between the 245 and 245M (or the 645 and 645M).
