I have a 04 XLR. I want to play my Ipod touch through the system. I have tried a few wireless ones but, I live between Chicago and Milwaukee (way too many stations to get a empty channel).
I have read past discussions on the ones that go through the xm system and displays on the screen. I heard of too many battery drainage issues and no good control of the ipod though the steering wheel buttons. (unless those are old posts and someone knows a good wired system that works properly, let me know)
Now, I am looking at a simple wired FM modulator (as seen on Ebay). it is just a simple connect through the antenna wire and a power\ground connection. I have done similar in the past with cd changers mounted in the trunk. What I am wondering is....
I included a pic of the kit.
are antenna wires still the same on the XLR radio to connect this kit?
I recommend the USA Spec "PA15-VETTE" as opposed to anything that transmits an FM signal.
I installed it about 10 months ago, and it works great. No strain on battery, and you have control from the radio and the steering wheel. It does display on the screen (there is a slight dealy) and even the windshield (HUD), but the XM preset buttons won't display the names of presets/folders. That's just a software design defect on the XLR FM module, because it doesn't display the names of normal XM presets either (although the Corvette does). There's a good review on Ray Kawal's Corvette site.
They no longer make the LockPicks and the GM PAL isn't currently available (and won't have all the functionality that it has in the Corvette because of the slight Preset Button differences from XLR that I mentioned above).
