So I got a Vida Dice setup from China. Got it installed on my laptop. went out to the 06 V70R and had nothing but problems getting it to talk to the car. Dice was saying pass thru error 8. Finally started the car and got it to talk. Looked at some things and got a feel for it. Shut the car off and went to position 2 and was able to talk. After about 30 minutes got a low battery warning on the dash so shut everything off and called it a night. Next day go out to try a sum calibration. could not get it to talk. Even with starting it and letting it idle for awhile to make sure the battery was charged. Got frustrated and went over to the wife's 03 S60 to see if my dice was bad. was able to talk in pos 2 with no problems. Now my question is does the battery condition affect the Dice interface so critically that I would have these problems? In addition any thing special I need to know before I put a trickle charger on the battery overnight? Thanks in advance.
