thomasjamesjr Posted November 12, 2014 Report Share Posted November 12, 2014 Hey all, new to the forum. I have a new 2015 optima that has XM radio installed. Going to purchase the AVH-4000NEX and was wondering if I still need to purchase the Pioneer xm tuner or if I will be able to just be able to save some cash and tap into the OEM tuner that came with the optima? Anybody have any info on this? Quote Link to post Share on other sites

thomasjamesjr Posted November 12, 2014 Author Report Share Posted November 12, 2014 Damn ok.. What tuner did you go with for the unit? Quote Link to post Share on other sites
joemamma1954 Posted November 12, 2014 Report Share Posted November 12, 2014 I got the svx200v1, from amazon, paid 40.00, comes with 3 months all access. Plug and play, check forum to see if you can use oem antenna, they do make adapters if needed. Works great. Quote Link to post Share on other sites
lombana Posted November 17, 2014 Report Share Posted November 17, 2014 I think that the aftermarket really needs to find a way to standardize OEM antennas or make adapters that won't have too much cable loss that you can run just like they do with the FM terrestrial radio antennas. I have an 07 Vette and purchased the SVX tuner as well and didn't like that I had to find a new location for an antenna and even run an antenna period considering there was one there waiting for me. The factory antenna didn't work for me but it would have been awesome considering on the vette the XM antenna is in the mirrors and I had to mount mine in the dash under where the old center speaker was located before I removed it. Sadly I get drop outs from something as simple as going under and overpass at 70 mph which really sucks but since there is no metal on the vehicle to mount to I didn't have many options.

Mr. Furious Posted November 17, 2014 Report Share Posted November 17, 2014 I'd have to see what the OEM connector looks like on a Corvette, but many OEM antennas can be retrofitted easily, without an adapter. Mine (on a Volkswagen Passat) could've been connected that way, but I opted for an adapter so that it would be easy to put the factory HU back in when I eventually sell the car. Any XM antenna will work with any XM tuner, it's just the connectors that have to be figured out. Heck, the OEM antenna in my VW is a Sirius antenna, and it works fine with the SVX200V1, which uses the XM satellites. Quote Link to post Share on other sites

My 07 Silverado oem antenna worked, all i had to do was remove the yellow plastic housing on the end of the antenna cable and it plugged right in. hard to believe the 07 vette would be different.

lombana Posted November 20, 2014 Report Share Posted November 20, 2014 OK I recall why I didn't or couldn't use the XM antenna in my 07, in the convertible the XM unit is located behind the drivers right arm in the area called the waterfall, in my standard C6 the XM is located in the B Pillar over the drivers left shoulder. I originally wanted to mount the S-XM unit back there but the control cable was only 18" long and I wasn't able to find an extension adapter. After realizing what it would take to mount the unit in place of the factory unit I just decided it was easier to mount the new unit in a small space right behind the radio and mount the antenna above the air vent in the center console. Aside from occasional drop outs like going under and overpass, it works, not 100% but the install is clean and it's not terrible. Quote Link to post Share on other sites

BRIAN_CFH Posted February 22, 2015 Report Share Posted February 22, 2015 Hey guys you can use the existing Sirius/XM antenna. You just need to remove the plastic housing around the factory plug. Then I just taped the cord to the be Sirius tuner to make sure it didn't come lose. Works perfectly. Quote Link to post Share on other sites
