Sounds like the little capacitor battery in the GPS isn't holding the data from the almanac and ephemeris anymore. Every power-on fix becomes a COLD fix, taking longer because of the requirement to receive the almanac and ephemeris data. I doubt it's related to the ROM update since the receiver is entirely independent of the X51. You might contact Arkon, or whomever sold you the receiver, to see if they would offer a replacement under warranty, or you could look at the BT units that are out. I wouldn't get a CF card with a BT powered PDA because there is no need to take up the slot with a GPS when you can use it with a big memory card to hold the program and maps.
