XM radio problem

My 2009 Taco came with XM antena Built in. when i installed the Navigation Head unit with Audiovox XM tuner (aftermarket) my installer could not use the factory Built in Antena, so he opted for external antena on the dash . I lose signal at lots of locations as i drive , in NJ . My installer also advised me the Toyota Fit Kit does not work with the Audiovox,Tuner Kit either, so i did not bother getting the Kit from the Dealer . Now I am also contemplating changing to Sirius Radio, which i think i have to get a whole new Tuner and internal antena??? Any suggestions. Thanx In advance

 

Move the antenna to the outside. Problem solved.

FWIW, on my last vehicle I had aftermarket equipment and had my XM antenna on the dash and it was fine and didn't cut out except for the normal trees or building blocking signal. Didn't work nearly good in the Tacoma when I installed an aftermarket HU a couple weeks ago with the XM Direct kit. I moved it to the front passenger side corner of the roof. Doesn't cut out at all now and I get better reception than I did with the factory Toyota XM crap.

 

This adapter will make your headunit work with the factory XM antenna...Have it on mine and works like a charm....
