GM wants $20.00 per mth for someone to tell you how to go from one location to another,
It's just not worth the cost. most folks know were they are going and how to get to their destination... (like if you don't know how to drive to work or vacation, then you got problems.)
plus if they do need assistance they can call either the AAA or CAA or learn to read a road map.
for a lot less dollars...
the computer software in most auto navigation maps are all outdated in a year or so, and just not worth the cost of replacement every other year. There is a new law coming down the road next year, no more analog signals, every one will be switching to digital,
that will make most of todays computer navigation equipment in to-days auto's useless. if they are installed in you car you won't be able to use them.
buyer beware. were has all the quality gone... cheers
