Iguidance 4 works fine with the Mogul (Stock rom, now no2chem rom) when loaded in main memory. Usign 6Gb SDHC for maps (1.3GB data for full US/Canada with POI). Boots quickly and allows switching to calls for incoming with/without BT. Was using a holux BT GPS for a while then switched to the Freedom GPS. No problems with either, although the cold start time varies alot for the GPS when traveling between states (i.e. if you boot the GPS in a new location far from the last lock position, it can take a while to locate satellites).

IG4 is faster than TOMTOM on the Mogul and gives much better directions (spoken street names and interstates) and also allows a demo run between points without the need to hook up the GPS.
