So, bought a used Packtalk Slim from another inmate, supposedly only used on a couple of rides, so I thought I would give it a try and see if it resolves any of the issues I have with my Bold. The main issue was the really crappy audio quality of music with earbuds. I can't get much volume at all without the low frequencies becoming very distorted. Another issue was the poor bluetooth radio that will disconnect if I'm 10' away from the tablet on my bike I have it linked to. So, every time you stop for photos are to take a leak, the music drops. Anyway, The Slim arrived, and it definitely has better audio quality, plenty of volume and low frequencies without distortion. Haven't tested the bluetooth range yet as a problem became evident that took up my evening trying to get it sorted. The first thing I did was connect the unit to my computer to check the firmware version, which was the current V5.2, I then did a reset to factory defaults, set the settings the way I have my Bold set and installed it on my XD4. Then I thought I would check the battery status, said "Hey Cardo, Battery Status" and got nothing, nadda, zilch. I've checked and rechecked the settings and volumes and it's all set correctly for voice commands. I put it back on the computer and toggled the settings on and off and re-synced, nadda. Tried the mic from my Bold, nadda. So I'm now at a lose and hopping someone here may have been through this and know what to do. I'm going to try to figure out if there is some way to reinstall V5.2 as I did have a weird firmware issue when doing and update with my bold where everything worked except it wouldn't pair to another unit. Mid trip I found a helpful guy in coffee shop that let me use their computer to do an update and it fixed the problem.
