The dealers are f'n crazy!!! They told me the same B.S. "It's gonna' take 6 hours and cost up to a thousand dollars to do." The woman tech admittedly had never even been inside an 07' yet. I knew more about it just from doing research. I like how they play on most consumer's ignorance by saying they have to pull the entire dashboard off and, blah, blah, blah, making it sound like it's so tedious. They say this because most GM techs are ignorant to most of the 2007's because they're so new and GM makes so many frickin' changes the techs can't keep up with it all. The techs are in the trenches all day everyday and don't really have the time to educate themselves on everything. Only about 1 in 10 are super knowledgeable. I'd just rather have a deal be straight up and say, "You know what, this thing is so new we don't have a clue right now. Give us a few months as we start to see more 07's and then we'll be good." Just something along those lines you know.

The funny thing is this. I've been a satellite and microwave engineer for the past 10 years now, so troubleshooting and wiring is pretty much what I do. Even with all of that, their are certain things I don't touch or do, even though I'm highly capable of doing them, I just feel like my execution may be poor. Now dealing with cars is one of them. I pretty much know what's up in theory, but would rather let the "professionals" do it as they're cracking open cars all day everyday. (Damn I'm long winded today! LOL.) Having said that after hearing how ridiculous the dealer was talking, I decided to do it myself. Let me tell you taking out the old head-unit and replacing it with the Nav, including installing the GPS antenna underneath the dashboard, took at best about half an hour. 6-8 hours my ***!!!

Sorry read your post and just wanted to vent and share.

PEOPLE!!!!!!!!! Ha, ha.

 

I will be doing my own install as well! However, I will take it to the dealer to have them program it!

 

On the question about why they might not just get one with Nav - well look at it this way. Maybe they are only approved for a certain amount and don't have the down payment or cash to cover the difference. The Nav is 1500-2000 upgrade depending on your discount if you get one. Anyway - just my 2 cents.

Big - go to the dealer, ask them to let you borrow a Tahoe with Nav, take you wife somewhere, get lost, then fire up the Nav and go back to the dealer! Maybe she will change her mind

 

Does anybody have the website for JB Customs where I need to get the plug in adapter for the voice controls? I did a web search with no luck. Thanks.
