Short answer: Yes ... but ...[cough] ...

Long answer: It's quite possible to do that, although questionably legal because you must manipulate the map IMG file so it can then be used in a different device, i.e. it must first be 'unlocked' because its GMA protection binds the map exclusively to the device for which it's been licensed. Bypassing that protection by stripping out the mapping data's GMA code is a breach of Garmin's EULA and accordingly we can't help you 'hands-on' in this forum. BTW, unless your busted 265W has an LM entitlement the detail map on it is going it be very out of date anyway so hardly worth the effort. However, there are several easy-to-find sources where you can obtain current maps and a tool to unlock locked maps - look for the file gimgunlock.exe - "Garmin Image Unlocker" along with a locked map, or even easier you can just search for an already unlocked version of the NA map you need. However, as i've already mentioned, we can't help you with that any further than just talking very generally about it like this. Of course, Google is certainly your friend and should point you in the right direction.
