Most people dont know it, but if your GPS has a PC connector, you can probably upgrade the internal ROM.
I just bought a GPS and checked the Garmin webiste, there were 3 updates to the BIOS that fixed probably over a hundred issues…
What this does is re-writes your GPS operating system to update to the newest that model has to offer…
Anyway, I have just never seen anyone talk about this so thought I would throw it out… Its a simple procedure (but can ruin your GPS if you do it wrong) but if anyone needs help give me a message !!!
