While aftermarket nav units are generally more "feature-rich" than OEM, you've made quite a blanket statement here. I'll assume you're trying to compare apples with apples (ie: in-dash units, not an in-dash compared to a windshield mounted unit). I'm not sure how you justify no headaches or worrying about if it will work. Virtually every in-dash aftermarket unit will have integration issues requiring one or more additional modules to retain functionality with OnStar, steering wheel controls, XM Radio and the warning chimes. Selection needs to be based on what the end user is trying to achieve. I had a TomTom and really liked it. I hated the "aftermarket" look and distraction of having it stuck to something on my car. Although my in-dash unit has fewer features, it gets me where I need to go and "plays nice in the sandbox" with all my OEM equipment.

you are correct in everything you said mainly...i'm just saying for the money you are better off going aftermarket imo. yes you need to buy some modules but the return is far greater than the expense. but lets try not to get off topic here.

there really is nothing to discuss

btw the links you posted on page one 404...

Is it possible to get the links to the nav unit installation up again?I would be interested in reading up on it

thanks

ck2001 if you use the search function i'm sure you could find them.
if not for some reason then ddalder needs to get off his bum and update/find/remake them!

Hi


Tried the search function and still cant find

Also wondering , would a newer nav radio using gm newer lan bus work on the Bonneville class II system? Is there a way of making it work?

Thanks
