New 4350 - Couple more questions

Thanks in advance.

When setting the home address, it's about 3/4 mile away. Anyway to
overwrite the "home" icon/info with true GPC coordinates from the "Where am
I" screen? There through, it lists a different address.

For the one touch shortcuts, I se I can address addresses, but can I add
something like "Starbucks" so when I touch it, it shows me the nearest
starbucks instead of clicking through the other menu items to find that
point of interest? I guess I am asking, can POI's be added to the one
touch?

Thanks again!!
