Lane assist on GPS

[ChaoZ]

I want the Garmin Nuvis that have lane assistance, but they cost ~$300 and I'm kind of confused on this whole concept. Does lane assist depend solely on the software or on the hardware also? I can understand if it requires better hardware, but if it's just software why can't they just update the maps on the older GPS or something?

It is software-dependent. They wouldn't give that feature to older model, so they can sell you the Lane-assist model for more money.

It is just the same thing with their non-tts model vs tts model. ( 205 vs 255 )
Hardware-wise, both model are identical down to the RAM size.
But the ROM is something no one able to crack yet.
Even if you copy entire folders, files from 255 to 205, it still will NOT perform TTS on 205.

yes yes guilty... I have tried to load a firmware image of 260 to 200, but I end up killed my perfectly working 200.

But if you are able to hack the rom, please don't hesitate to share.
