It's a matter of personal opinion i suppose, but i reckon flashing 465 firmware is preferable to flashing SG/MY to a HWID 0827 device. Still get LA and no problems with TTS. You lose the little north pointer and the side bar stuff but everything runs normally. The SG is just too buggy on a US 2x5W device for my money. I've loaded it again to one of my 255W>465 convert units to re-convince myself. I still think it's pretty cp*p, so gonna flash it back to 465 right now. 465 gets the second map in SD card too and the truck profile is a bonus for some.
