Not really, The problem with the older radio is that the way they fed the power to the mp3 side was to back door it through the FM modulator, thus resulting in a lower volume than theradio. Unfortunately there is no fix for it.

I have purchased a bike which had the Road tech HA90 MP3 / WMA Digital Music Player on it. Okay this has been an ordeal getting it to work. Cannot locate a instruction manual or the operation manual , I relied solely on Internet Search and mostly this web site. Here is what I have done. First used a 4G Micro SD Card - formatted to Fat 32 ...nothing...nothing seen or recognized... err no all sorts of errors...NEXT a friend has a player so rode over checked his card in my player and all is well ...HIS card is a 512 mb.IT WORKS PERFECT !!!! NO 512 SD Cards anywhere...the lowest 4GB. (Unless you order online) I have seen somewhere that someone wrote that 512 was the largest ...then another has wrote nothing over a 2G ...Now since I do not have a manual looked back at catalog page and it came with 64mb ..best of both worlds I have been able to by chance locate a 1GB SD Card locally . They no longer make cards under 4GB or stores do not carry around here, but can get on Amazon...Okay back to the issue. NOW TRYING THE 1GB card in Fat format / then reformat to FAT32 Tried it and the player recognizes the card tells me the number of songs I have on the card , is going thru the motion but NO SOUND.....now what???? I plan to get with friend and check info on his card regarding format etc. since it works, and order a 512 mb card ..HOWEVER Does anyone have the magic potion to offer advice on what to try next??? Thank you
