My pleasure! It's a little OT here, but yes you can convert your 255W if it's HWID 0827 only [don't try if it's MTK chip though, from memory that's HWID 1091]. Use only the original US boot bin though rather than flashing the full SG fw and there are other precautions. There is a thread somewhere in here i recall. You may be disappointed with the results, lousy TTS voices for a start and display of JCV is flaky anyway. You do get LA, displayed differently to US/EU type lane assist, and highway mode [i think] too. I've converted my 255W & my son's 265W to SG and then back to US and then finally converted to 465T truckie's nuvi with LA etc [no jcv but all else works perfectly] again using 2x5W boot.bin.
