i own a thick paper 2 book set of 07 and a downloaded version of the same to carry on my comp.
now i try to get the latest and keep getting copies of 07/08 when the 09 is advertized.
these are cheap knock off copies on a cheap cd but no late model stuff,blue thhth,other ent info. no locking diffs and,,,what else am i missing??

a legit link would be appreciated, and yes i know,im the one who tells everyone to buy a manual!. now im trying, cant find the latest.
if you say ebay know that ive tried 2 from there so far

4pm,,i called Helm,they otta know huh, sounded helpless, gave me the # for gm cust service, totally helpless!! gave me a # for where they go for help, a glorified used book store!!
