03-19/2015 - UPDATE to the 2014-2015 Harley Infotainment Systems Flash Issue.

After having numerous radio flashes performed at our local Harley Dealer, & now with more than 35 ROKKER audio system installs/flashes at the J&M audio trailer during Daytona Bike Week, I have a much better look at this entire issue.

1) J&M Brand ROKKER series & Performance series amplifiers are currently preset for the stock Harley radio flash as ((Under SPEAKERS TAB: Number of amps 0, 2 or 4 speakers CHECKED, Under OPTIONS TAB: Amp 2 Installed? CHECKED NO, Amp 1 Installed? CHECKED NO)) which is how most if not all of the 2014-2015 radios have been delivered stock from Harley, (with the CVOs being the exception to this), so there is NO reason to have the stock Harley radio re-flashed when installing the J&M brand speakers & amplifiers.

2) When installing other non-Harley brand speakers/amplifiers, simply adjust the amplifier input gain & frequency response curve settings to optimize the available volume and clarity, just as you would do with a standard automotive type radio, regardless of how the Harley radio is flashed, and if you change the radio flash at a later date, then simply re-optimize the amplifier input gain/frequency response settings.

3) For the New J&M ROKKER XX Extreme & Performance Extreme installation KITS http://www.jmcorp.com/SeeProducts.asp?PF=55 & http://www.jmcorp.com/SeeProducts.asp?PF=56 as of this date, are going to be offered pre-set for the BoomBox 6.5GT premium & 4.3 standard radio, with the REQUIRED special Harley radio flash as ((Under SPEAKERS TAB: Number of amps? SELECT 0, then CHECK BOX for 0 amps, 4 speakers, Upper Fairing/Rear pods. Under OPTIONS TAB: Amp 2 Installed? CHECK YES, Amp 1 Installed? CHECK YES)) and this particular Harley radio flash will automatically activate the front/rear fader control. And while your dealer is performing these updates for you, I would also check YES to the Intercom, Bluetooth and CB under the options tab. ((see actual computer screen shots here. http://www.jmcorp.com/PDF/HarleyRadioFlashUpdate03-19-2015.pdf

4) This special Harley radio flash combined with a properly adjusted J&M ROKKER or other brand amplifier, will provide superior sound & clarity, compared the current stock Harley radio flash.

5) These new special J&M ROKKER XTP amplifier DSP software programs designed for this special Harley radio flash as ((Under SPEAKERS TAB: Number of amps? SELECT 0, then CHECK BOX for 0 amps, 4 speakers, Upper Fairing/Rear pods. Under OPTIONS TAB: Amp 2 Installed? CHECK YES, Amp 1 Installed? CHECK YES)) will be available on the J&M ROKKER XTP software download webpage http://www.jmcorp.com/static/rokker-downloads.htm within the next 14 days, for those of you who already have a J&M ROKKER XTP amplifier and wish to re-flash your Harley radio to this special flash & update your J&M ROKKER XTP amplifier settings.

We will be providing further updates as they become available. JMJOHN – [email protected]

We are here in Phoenix at AZ bike week ,,,,,,,

I just walked out of our trailer and played with our 2014 SteetGlide 500w 6 speaker ROKKER XX system which has the radio flashed exactly like I specify in item 3 of the flash instructions here http://www.jmcorp.com/pdf/HarleyRadi...03-19-2015.pdf ,,,,,,,

The radio's bass, treble, fader and AVC controls all function as normal, although I will say that there is not quite as much RANGE of control for either the bass or treble, compared to the stock radio flash ,,,,,,,,

This new J&M recommended flash when performed correctly, enables all radio adjustment functions, as well as altering the internal EQ so that you can run MAXIMUM volume on the radio on most of your music tracks WITHOUT significant amounts of bass distortion ,,,,,,
