Installing Old Style Antenna On 07 Denali

[tommbo]

I have a 2007 Denali and my fm radio reception stinks! They use a new style antenna mounted in the rear window. My question is..can I install the old style mast antenna without drilling the fender? Also what is the GM part number for this mast antenna? Thanx for your help...

You should have just as good reception from the window antenna. You may want to go to the dealer and see what the problem is.

Note: The only way to order a replacement wrench is to order a new antenna mast assembly.

Since your vehicle is under warrenty i would suggest you take it in to the dealer. If you break anything YOU will have to pay for it if they do they pay for it. Also if you fix it there is no tracking of the problem for GM to know and correct the problems.
