Edit: OMG, street view works too!
it seems you have technical knowledge of java better than myself.
so for increasing heap space, i suggest you contact davy directly as creator of PhoneME (all credits goes to him as i've always recited)

I poked around and couldn't figure out how to pass max heap size to cvm through runmidlet, maybe there is a cleaner way but I ended up using the full command line for the Exec property in my googlemaps.desktop file, notice the -Xmx parameter which now sets max heap size to 24m instead of default 12:
With this value I couldn't trigger the low memory condition which used to occur fairly soon after enabling traffic and zooming in/out several times. In theory this may help to speed up the app somewhat as the garbage collector doesn't have to run full sweeps as often.

Code:
Exec=/opt/phoneme/bin/cvm -Xmx24m -Xbootclasspath/a:/opt/phoneme/lib/jsr234.jar -Dmicroedition.profiles=MIDP-2.1 -Dmicroedition.location.version=1.0 -Dsun.midp.library.name=midp -Dsun.midp.home.path=/opt/phoneme/midp/midp_linux_fb_gcc -Dcom.sun.midp.mainClass.name=com.sun.midp.main.CdcMIDletSuiteLoader sun.misc.MIDPLauncher -suitepath /opt/phoneme/googlemaps.jar -jadpath /opt/phoneme/googlemaps.jad -1 com.google.googlenav.GoogleNav

Dang, can no longer run the app. It attempts to show the Terms and Conditions screen on launch and then craps out with a "serious error" message. Anyone else has this problem?

Weird, I've installed a couple of apps since I was able successfully run it last time. Uninstalled them and it didn't help. Do you remember seeing "terms and conditions" screen? I don't, even if was shown initially it is unclear why it is being opened again. Maybe it stores a file with persistent settngs which is now corrupt. hmm.

I removed my changes from the desktop file but no use. Wondering if yours will stop working the next time you see the T&C screen.

Is it possible that some of the components that cvm depends on got replaced with other versions because I installed some apps which broke cvm (java vm)?
