Actually, Google Maps is, in fact, available in the Android Market. First thing's first--STOP AUTOKILLING APPS. You really need to let Android 2.2 manage memory on its own. I raaaaaaaaaaaarely kill apps to start with and it's been documented all over the Internet that with 2.1, task killing was a necessary evil that killed the battery, but with 2.2 you no longer needed an automated task killer because memory was freed up as necessary and actually helps increase battery life FAR better than an automated task killer (which actually made battery life worse). Second, assuming you have a rooted Galaxy Tab, you can use Titanium Backup to FIRST: back-up your copy of Google Maps. SECOND: Uninstall Google Maps using Titanium Backup (even OS apps can be uninstalled using TB). THEN, go to the Android Market and reinstall Google Maps. Lastly, Why is it crashing? I doubt that uninstalling and re-installing will fix that. What is the symptom and how does it crash? Maybe we need to triage the issue before we jump to conclusions about a cure for the problems.
