Yes i have the problem with Clarion system clock too. Bought VXL in last October. the problem with clock is, even i set the clock, next day morning, when i start the car, it is reset again to 00:00. i went to Suzuki dealer on its 1k milage (free inspection). they first check the battery gravity. but i know, there is no problem with battery, its the clock.
so, fianally they asked me to sign a form so that they may send the claim. till now, i am waiting for any reply.
I think, it is the faulty lot of Clarion deck systems, received by Suzuki and fitted in cars. Suzuki cannot do any thing, except repalce the Clarion deck. Which they will not, i know (really Suzuki walon nay Choona lagaya hai).
