Default 2008 GMC Canyon

I own two Tram antennas with 5 inch magnetic mounts, CB & Scanner. I am attempting to install a Cobra 29 Classic somewhere under the dash.

I forgot to mention this is a Canyon Crew Cab with moon roof.

I would appreciate any recommendations regarding CB placement.

Also, where can I run the coax cables to avoid shutting the door on them? I have looked for grommets to no avail. The only location I can place my magnetic mounts is toward the back. Due to the grooves on the roof, it is rather difficult to set the magnet flat. At present, they have not left the roof, yet.

I read something about "cab vents" but I don't know whether I can find them due to bed liner.

Help.

I had a 2005 Canyon extended cab and have a 2007 Colorado extended cab at work. My dad had a 2005 crew cab for many years, too.

I've done permanent NMO mounts on all of them.
I understand the desire to use magnetic mounts, but they are not going to do you any favors.
The rear cab vents can be used, but it creates a couple of issues:
1. The cab vents won't be able to close all the way with cable running through it. This may be an issue with wind noise, moisture, bugs, etc.
2. You'll have to cut the connectors off to fish the cable through.
May not be a concern for you, might be a good solution.

On the other hand, the NMO mounts are pretty easy to install on these trucks. The rear edge of the cab roof is a good location. While not a great ground plane under the CB antenna, you'd be limited by the mag mount/sun roof combination only. Removing the rear high mount brake light gives you good access for routing the cables. Easy enough to bring them down the back inside of the cab and to the radios. Looks clean, no issues with magnets damaging the paint or routing loose coax cable.

AS for where to mount the CB… Kind of limited on these. Under the dash is about it. I had two radios mounted under there on mine, a VHF and UHF mobile.

For 12 volt power, it's pretty easy to run a power lead direct from the battery. There's a big grommet on the drivers side firewall. Making a small hole on the outer edge of that grommet will give you an easy path. Route the + lead direct to the battery + post, fuse close to the battery. As for the - lead, I discovered that if you tie the negative directly to the battery negative post you can often pick up alternator whine. Moving the negative lead to the vehicle body ground just behind the battery eliminates the interference. Discovered this on all 3 of the Canyon/Colorado's I've installed in.

Well, I tried to post Photos, but PhotoBucket is being cranky.

Likely going with hump mount, keeping magnetic antennas, maybe later on permanent mount. Thanks.
