Blakt Out

Hey guys,

I'm at the stereo shop right now. We're putting in a new Sony Nav double din head unit, a sub amp, subs, a 4 channel, and some components. The adaptor that they have gotten for the car apparently will cause me to lose all Class 2 data. What all is this? Anyone know? If it's just OnStar, that's great. I just don't need to be having any big issues. Any and all help is VERY appreciated. Especially expert RAPID help!

Oh, it's an '04 CTS-V.

Thanks,

Jared

Your gonna lose all your customizations, and probably competition mode....the nav is a big part of the car....better to leave it hooked up but installed in the trunk...gonna be a pain to extend all those wires though.

Yea, they mean your gonna lose all of your on screen notifications, leaving tuen signal on, low gas, comp mode etc etc etc. Sucks to have to give it up but the stock unit is WAY outdated.

OK. I really appreciate it guys. I didn't even think about Comp mode. That's huge for me, as I will be tracking the car a lot and drive it in Comp mode at least 70% of the time just here on the backroads of Tennessee.

They assure me that the adaptor thing will keep all the Class 2 stuff in tact though. I even called Crutchfield and they said the same. Are you guys positive that I'll lose this?

I meant you would lose the screen prompts most liekly, not sure youll actually lose the functions though.

I'd leave it stock but that's just me.

^yeah that or you could get the non-nav regular cts DIC that will still show you messages and let you in to COMP mode. It's a win win then.
